Abstract:

This article discusses that although it remains the worst maritime disaster in the US history, the Sultana explosion was not an isolated incident in the United States. Boiler explosions occurred with alarming frequency, not only on board steamboats, but also in factories, mines, sawmill, and woodworking shops. Legend has it that the group came together expressly to address the problem of unsafe boilers, but the initial objectives of ASME were modest. The founders were seeking a reliable system for technical information exchange as well as a social setting. The publication of the first ASME Boiler Code in 1914 was a symbolic moment in the history of the Society, an event that would help define the organization and contribute to its stature and importance in the mechanical engineering community for decades to follow. Ninety years later, the Society today has approximately 3400 active volunteers working on committees that combine to issue more than 600 standards. The standards detail the proper dimensions of a wide range of manufactured objects, from pressure vessels and piping to screw threads. However varied they are, they serve a single purpose: to make sure that all the pieces fit and hold together safely, even under pressure.

Abstract:

Research since the 1960s on the deposition of droplets from wet steam is reviewed, concentrating mainly on low-pressure turbines but also covering the limited work related to nuclear high-pressure turbines. The context is first set, outlining the motivation in terms of blade erosion and, to a lesser extent, wetness losses. Details of measurements in turbines and in simulated turbine flows are followed by descriptions of theoretical work on the main inertial and turbulent deposition mechanisms; possible additional contributory mechanisms are summarized. A major combined experimental and computational effort in the 1980s led to broad agreement between measured and calculated fog deposition fractions in low-pressure turbine final stages, attributed largely to the development of more accurate droplet size measurement and computational fluid dynamics techniques. An attempt has been made to correlate advances with the history of steam turbine development and to speculate on the future of deposition studies in the light of recent theoretical developments and trends in power generation.

Abstract:

The diffusion of steam into the transatlantic migration system of the nineteenth century, one of the most important developments in the history of human demography, is often explained by the technical progress of ships, which made the carrying of migrants under steam profitable. Existing historiography posits that early, basic paddle steamers were sustainable only with government mail contracts, whilst iron screw steamers later facilitated the emergence of a mass migrant trade. Data on steam company formation, durability and accounting for the mid-nineteenth century show that technical thresholds are not sufficient to explain the transfer to steam shipping of migrants. Determining factors were inter-regional relationships connecting engineering and demographic change, and, critically, the abandonment of capitalising novel steam lines. This article demonstrates that steam became usable because of endogenous transfer within well-established sailing services, a pivotal strategy adopted by those connected to centres of both innovation and migration.

Abstract:

This contribution attempts to clarify the relationship between the practice of plurilingual education and STEAM (interdisciplinary pedagogy that incorporates science, technology, engineering, art, and mathematics) through the lens of peace learning at an elementary school in Japan. Japan has a rich history of peace education, although it has received limited focus in the international literature, whereas plurilingual education remains relatively unknown in the country. Within this context, the article examines a teacher-initiated plurilingual and intercultural project focused on a multidisciplinary approach to peace learning. Analyses of multimodal data, including video recordings, photographs, researchers' field notes, learners' journals, and semi-structured reflective interviews, will demonstrate how even within a highly homogenous context, practitioners can promote transferable skills and nurture a deeper awareness of language and openness to diversity, foster reflexivity, and encourage multidisciplinary engagement through plurilingual education, dialogue, and storying.

Abstract:

This article discusses how kinematic mechanisms created by Franz Reuleaux are now being made available by Cornell University for students and researchers. The university’s Sibley School of Mechanical and Aerospace Engineering owns the largest set of cast iron and brass models of machines designed by Reuleaux more than 130 years ago. Cornell librarians have helped develop the Kinematic Models for Design Digital Library, or K-MODDL, to allow Internet users to view the models close up. The Cornell Reuleaux Collection contains numerous kinematic mechanisms for rotary and reciprocating engines using both steam and internal combustion. It also includes a dozen working clock escapement mechanisms, from the early verge and foliot escapement to the gravity escapement employed in London’s famous Big Ben. K-MODDL will make the collection available to educators, researchers, and students well beyond the Cornell campus. Those with access to a 3-D printer will be able to build a reproduction of the real thing to see up close how the mechanism works.

Abstract:

In this paper, we describe an educational experience in the context of the Master’s degree that is compulsory in Spain to become a secondary education mathematics teacher. Master’s students from two universities in Madrid (Spain) attended lectures that addressed—emphasizing the concourse of a dynamic geometry software package—some historical, didactic and mathematical issues related to linkage mechanisms, such as those arising in the 18th and 19th centuries during the development of the steam engine. Afterwards, participants were asked to provide three different kinds of feedback: (i) working on an assigned group task, (ii) individually answering a questionnaire, and (iii) proposing some classroom activity, imagining it would be addressed to their prospective pupils. All three issues focused on the specific topic of the attended lectures. In the framework of Mason’s reflective discourse analysis, the information supplied by the participants has been analyzed. The objective was to explore what they have learned from the experience and what their perception is of the potential interest in linkages as a methodological instrument for their future professional activity as teachers. This analysis is then the basis upon which to reflect on the opportunities (and problems) that this particular bar-joint linkages methodological approach could bring towards providing future mathematics teachers with attractive tools that would contribute to enhancing a STEAM-oriented education. Finally, the students’ answers allow us to conclude that the experience was beneficial for these pre-service teachers, both in improving their knowledge on linkages history, mathematics, industrial, technological and artistic applications, and in enhancing the use in the classroom of this very suitable STEAM context.

Abstract:

The time history of steam pressure inside an isolated spherical micro-cavity in a polymer matrix composite is studied by assuming that the chemical potential of water is continuous across the cavity–polymer interface. Steam pressure inside the cavity is due to heating of moisture-saturated composites from its initial temperature to a final temperature. Exact closed form solutions are obtained for the steam pressure developed under infinitely fast heating in an infinite plate. The effect of cavity shape on the induced steam pressure is studied by comparing this solution with a previous result on cracklike cavities.

Abstract:

AbstractDirect steam injection is a sterilization technique which is often used for high-viscosity fluid food, when the preservation of the quality characteristics and energy efficiency are the priority. In this work, an apparatus for the sterilization of tomato concentrate has been analyzed by means of a 3D computational fluid dynamics (CFD) model, in order to optimize the exchanger performance in terms of temperature distribution inside the product. A multidimensional two-phase model of steam injection inside a non-Newtonian pseudoplastic fluid was adopted to evaluate the thermal history of the product and the condensation rate of the steam injected in the heat exchanger during the thermal process. Subsequently, the CFD analysis has been extended to examine the effects of the different process parameters (sterilization temperature, steam flow rate, radial and axial temperature profiles and nozzle geometry) on the resulting product. Results obtained allowed to understand the effects of process parameters on the behavior of the condensing steam and obtain better performance of the exchanger in terms of temperature distribution of the treated product.

Full text

Abstract:

A novel workflow is presented for integrating fiber optic Distributed Temperature Sensor (DTS) data in numerical simulation model for the Cyclic Steam Stimulation (CSS) process, using an intelligent optimization routine that automatically learns and improves from experience. As the steam–oil relationship is the main driver for forecasting and decision-making in thermal recovery operations, knowledge of downhole steam distribution across the well over time can optimize injection and production. This study uses actual field data from a CSS operation in a heavy oil field in California, and the value of integrating DTS in the history matching process is illustrated as it allows the steam distribution to be accurately estimated along the entire length of the well. The workflow enables the simultaneous history match of water, oil, and temperature profiles, while capturing the reservoir heterogeneity and the actual physics of the injection process, and ultimately reducing the uncertainty in the predictive models. A novel stepwise grid-refinement approach coupled with an evolutionary optimization algorithm was implemented to improve computational efficiency and predictive accuracy. DTS surveillance also made it possible to detect a thermal communication event due to steam channeling in real-time, and even assess the effectiveness of the remedial workover to resolve it, demonstrating the value of continuous fiber optic monitoring.

Abstract:

Architecture practice is reshaped by new technological developments such as virtual reality, augmented reality, 3D printing, computational design, robotics, etc. Future architects are expected to deliver spatial solutions, to understand changing living conditions and to discover the different future by responsing technological improvements. In architecture schools, students should explore and investigate design practice with different production methods, systems and materials by using various technologies in collaborations with interdisciplinary partners and industry. The study aims to understand the STEAM concept which is considered as a promising education approach and formulated; science, technology, engineering, math and then adds an ‘A’ for arts which represents the creative thinking and design approach. The STEAM concept and its place in the architectural education are discussed. The discipline of architecture is an intersection of technology, art and science. The architecture schools' curriculum reflects the interdisciplinary STEAM nature throughout the history. Virtual Reality (VR) is created through interdisciplinary technology and has the potential to prepare the students to future, to develop analytical and abstraction abilities.

Abstract:

This study is concerned with assessing the integrity of cracked steam turbine rotors components which operate under cyclic loading conditions. Damage accumulation and growth have occurred on the inner surface of slot fillet of key and in a disk and blade rivet attachment. Full-size stress-strain state analysis of turbine disk was performed for different stage of lifetime under considering loading conditions. As a result accumulated damage in critical zones of turbine disks depending on time of loading is defined. The tensile tests were performed for determination the main mechanical properties of disk’s material after loading history. The smooth and notched specimens were cut out from critical zones of turbine disk with given operating time. The low-cycle fatigue tests were performed with the harmonic test-cycle. Additional tests were performed on special designed program test-cycle, which equivalent to start-stop cycle of turbine disk. An engineering approach to the prediction of residual lifetime of turbine disks which is sensitive to the loading history at maintenance is proposed. Approximate estimations of carrying capacity are presented for the different stress-strain state of steam turbine disks at the operation.

Abstract:

A thermal stress analysis (TSA) technique had previously been developed to determine the heat history and effective heat set temperature of Suessen heat set nylon 66 carpet yarns. In this investigation, the Kanebo KE-2L thermal stress tester was used with yarns heat set with the standard and energy conservation package (ECP) Suessen units. In each sample set, the greige carpet yarns had been subjected to changes in heat set temperature, flyer speed, and steam pressure. The KE-2L accurately measured the effective heat set temperature and heat history of the yarn samples. Low standard errors of prediction and high multiple coefficients of determination ( R2) between the TSA-determined and Suessen heat set temperatures were obtained for both the standard and ECP Suessen yarns. The major Suessen heat setting variable influencing the TSA results is heat set temperature. For the standard Suessen yarns, flyer speed and steam pressure influences on the TSA results were minor and nonsignificant. For the ECP Suessen yarns, the small changes induced in the yarn from flyer speed and a heat set temperature/steam pressure interaction were significant, though still minor, and were measured by the TSA.

Abstract:

Rotor-to-stator rub is a very common topic in rotor dynamics and several models have been proposed in the literature. Anyhow these models are often able to explain only the experimental dynamical behaviour of simple test rigs, which are deliberately reproducing a Jeffcott rotor. On the contrary case, histories related to real machines are seldom presented and analysed. The aim of this paper is to present an actual case history of a large turbogenerator unit that was subjected to partial arc rubs. The experimental results are shown and discussed along with the model-based diagnostic strategy employed to identify the fault severity and the location of the shaft cross-sections where the heaviest rubs occurred. Comparisons between experimental data and simulated vibrations caused by the identified fault are shown to validate the proposed methodology.
