Streszczenie:

CFD (computational fluid dynamics) has become readily accessible and is widely applied in many aspects of the processing industries. A short introduction to CFD has been included in undergraduate Chemical Engineering courses with the aim of giving students an appreciation of its principal features. This comprised three lectures followed by practical experience of commercial CFD software applied to four simple fluid flow problems. A leading aim of the course has been to encourage a sceptical approach to initial results and to indicate methods by which their validity should be established.

Streszczenie:

Chemical Engineering as a distinct engineering discipline is now more than hundred years old. It was 1888 when Professor Louis Mills Norton first introduced the curricula for Chemical Engineering at MIT. As creative chemists came up with new chemicals it provided ever new challenges to the Chemical Engineers to innovate new industrial processes applying the new found knowledge in unit operations, unit processes, reaction engineering, process control, (later) transport phenomena and (recently) process integration. In Bangladesh the founding fathers of engineering education took a long term view of the industrial development prospects and took the innovative decision to introduce Chemical Engineering curricula in the erstwhile Ahsanullah Engineering College in the early fifties. During these early years large corporations in the public sector provided the initial thrust for development of chemical and process industries. However it was not adequately appreciated during the formative years that mere experience in the successful operation of complex chemical plants does not constitute technology transfer in the real sense of the term. Professional in the field stressed the need for setting up of design sections where local chemical engineers with inputs form relevant professionals would be able to contribute meaningfully in establishing the design criteria for a plant. In the private sector Chemical Engineers have demonstrated in Bangladesh that they can be innovative in transferring technology and developing Ceramic and medium scale Basic Chemical industries. Thus, it has been amply demonstrated that accumulating technological capacity through such dynamic technology transfer efforts should be one of the avowed objectives of any development process. Professional Capability and Areas of Competence of Chemical Engineers have grown over the years in this country and this issue has been elaborated with specific examples.DOI: http://dx.doi.org/10.3329/jce.v26i1.10174 JCE 2011; 26(1): 1-8

Streszczenie:

Models of electrochemical sensors play a critical role for electronic engineers in designing electrochemical nanosensor-based integrated systems and are also widely used in analyzing chemical reactions to model the current, electrical potential, and impedance occurring at the surface of an electrode. However, the use of jargon and the different perspectives of scientists and electronic engineers often result in different viewpoints on principles of electrochemical models, which can impede the effective development of sensor technology. This paper is aimed to fill the knowledge gap between electronic engineers and scientists by providing a review and an analysis of electrochemical models. First, a brief review of the electrochemical sensor mechanism from a scientist’s perspective is presented. Then a general model, which reflects a more realistic situation of nanosensors is proposed from an electronic engineer point of view and a comparison between the Randles Model is given with its application in electrochemical impedance spectroscopy and general sensor design. Finally, with the help of the proposed equivalent model, a cohesive explanation of the scan rate of cyclic voltammetry is discussed. The information of this paper can contribute to enriching the knowledge of electrochemical sensor models for scientists and is also able to guide the electronic engineer on designing next-generation sensor layouts.

Streszczenie:

The engineers have been utilising artificial neural networks (ANNs), one of the most effective and adaptable tools offered by artificial intelligence, for many years in a variety of applications. A simple mathematical model of brain functions is provided by ANNs, which are computational tools. They can be used for tasks like modelling, categorisation, and prediction when combined with raw data and a learning system. They have recently experienced a sharp increase in popularity and are currently among the most important study topics in the disciplines of artificial intelligence and machine learning. Large groups of basic classifiers known as neurons make up an ANN. Chemical engineers use them to automate process controls, model complex linkages, and forecast reactor performance. Large data sets can benefit from ANNs' capacity for learning, but these systems can also overfit or become stuck in local minima and are challenging to reverse engineer. The function of artificial neural networks (ANNs) in chemical engineering is explored in this article. For creating chemical engineering processes, the ANN is quite helpful. The process is very quick and trustworthy. We also gathered several journal publications and current research articles, summarising the use of ANN in various chemical engineering fields and its processes.

The paper deals with the problem of effective mathematical training of prospective chemical branch engineers. The chemical branch is one of the key branches of the Samara Region economy. The authors note that petrochemical enterprises need engineers who have sufficient all-professional and special knowledge, skills, as well as a high degree of professional mobility, able to react quickly and creatively to inquiries of dynamically changing practice; able to solve all range of production problems. The authors also note that the high level of professional competence of a chemical branch engineer is defined by the level of his/her mathematical knowledge. The authors reveal features of integral and differential calculus application for the solution of chemical tasks on the example of physical chemistry tasks. The authors suppose and prove that education process optimization and professional orientation of mathematical training in a technical college can be reached at the expense of such factors as: continuous mathematical training; modification of educational and methodical support; professional development of pedagogical staff; optimally structured content of mathematical disciplines by practice-focused tasks application intensification; motivation for mathematical disciplines independent study by students of a technical college; application of diagnostic techniques of students mathematical competence development.

Streszczenie:

Active learning strategies (including simulations) have been promoted by engineering education reformers as an effort to move traditional STEM teaching toward more constructivist practices. In this study chemical engineering students were studied during the implementation of simulators to promote critical thinking. While many have studied achievement and perceptions of students to measure engineering tools and their development, this study specifically examined students’ outcomes connecting the tool to specific teaching and learning strategies. A case study was conducted using pre- and post-test, survey questionnaire, individual interviews, and classroom observations. Results showed the use of simulator was associated with increases in students’ scores but the novelty of innovation was not the single explanation for increased scores or favored technology usage. Interviews and other qualitative data suggested that outcomes may closely tie teaching strategies to the effectiveness of the tool rather than the focus on the tool itself. Implications for teaching and future research are discussed.
