Abstract:

This paper tests various propositions underlying claims that observed global temperature change is mostly attributable to anthropogenic noncondensing greenhouse gases, and that although water vapour is recognized to be a dominant contributor to the overall greenhouse gas (GHG) effect, that effect is merely a “feedback” from rising temperatures initially resultingonlyfrom “non-condensing” GHGs and not at all from variations in preexisting naturally caused atmospheric water vapour (i.e., [H2O]). However, this paper shows that “initial radiative forcing” is not exclusively attributable to forcings from noncondensing GHG, both because atmospheric water vapour existed before there were any significant increases in GHG concentrations or temperatures and also because there is no evidence that such increases have produced measurably higher [H2O]. The paper distinguishes between forcing and feedback impacts of water vapour and contends that it is theprimaryforcing agent, at much more than 50% of the total GHG gas effect. That means that controlling atmospheric carbon dioxide is unlikely to be an effective “control knob” as claimed by Lacis et al. (2010).

Abstract:

This paper describes flow visualization and heat transfer experiments conducted with a heat source inside an isothermal cube filled with a saturated or near-saturated gas/vapor mixture. The mixture was formed by vaporizing liquid from the surface of the heat source, and allowing it to condense on the surfaces of the cube, which was initially filled with a noncondensing gas. Visualization studies showed that for air and ethanol below 35°C, and for air and water, the flow patterns were similar with the hot plume rising from the source. For air and ethanol above 35° C the flow pattern reversed with the hot plume flowing downward. For temperatures spanning 35° C, which is the zero buoyancy temperature for the ethanol/water azeotrope and air, no distinct pattern was observed. Using water, liquid droplets fell like rain throughout the cube. Using ethanol, a fog of droplets moved with the fluid flow. Heat transfer experiments were made with water and air, and conductances between plate and cube of around 580 W·m−2·K−1 measured. Agreement between the similarity theory developed for saturated gas/vapor mixtures, and correlations for single component fluids only, was very good. Together with qualitative support from the visualization experiments, the theory developed in a earlier paper deriving a similarity relationship between single fluids and gas/vapor mixtures has been validated.

Abstract:

Data are reported for condensation of steam with and without the presence of air on three rows of integral-fin tubes situated in a bank of plain tubes. The data cover a wide range of vapor velocities and air concentrations. Unlike previously reported data for plain tubes using the same test bank and apparatus, the heat-transfer coefficients for the finned tubes were largely unaffected by vapor velocity. When compared to a plain tube of fin-tip diameter and at the same vapor side temperature difference, heat-transfer enhancement ratios between 3.7 and 4.9 were found for the finned tubes compared to a plain tube in quiescent vapor conditions, while values between 1.9 and 3.9 were found when compared to a plain tube at the same vapor velocity. When compared to the plain tubes, the heat transfer to the finned tubes was much more susceptible to the presence of noncondensing gas (air) in the vapor, with enhancement ratios falling as low as 1.5 compared to the plain tubes when even small concentrations of air were present.

Abstract:

A study of plane, underexpanded, condensing vapor jets was undertaken using flash photography and a ventilated pressure probe. This study examined horizontal jets with much lower condensation driving potentials than have been previously studied. Photographic measurements of jet expansion angles, spread angles, cavity lengths, and cavity shapes were recorded and compared with numerical predictions using a parabolic, locally homogeneous flow model that had been modified to incorporate entrainment and condensation effects. When rendered dimensionless by the nozzle width rather than diameter, the plane condensation length agreed well with previously published round jet correlations for higher condensation driving potentials. At lower condensation driving potentials, the jets began to disperse, showing behavior similar to submerged air and energetic reacting vapor jets. Numerical predictions of condensation length were in good agreement over the entire range of measurement. Numerical predictions of vapor cavity shape were in reasonable agreement at higher condensation potentials but underpredicted the width of the vapor cavity at lower potentials. Pressure measurements showed the existence of periodic expansion/compression cells associated with underexpanded noncondensing gas jets. When these measurements were compared with similar measurements of air jets into quiescent water baths, the lengths of the initial steam vapor expansion/compression cells were substantially greater than those of the air jets, and the degree of pressure recovery over the cell length was substantially less.

Abstract:

In most earlier experimental investigations of condensation on low-fin tubes, vapor-side heat transfer coefficients have been found from overall (vapor-to-coolant) measurements using either predetermined coolant-side correlations or “Wilson plot” methods. When the outside resistance dominates, or is a significant proportion of the overall resistance, these procedures can give satisfactory accuracy. However, for externally enhanced tubes, and particularly with high-conductivity fluids such as water, significant uncertainties may be present. In order to provide reliable, high-accuracy data, to assist in the development of theoretical models, tests have been conducted using specially constructed plain and finned tubes fitted with thermocouples to measure the tube wall temperature, and hence the vapor-side heat transfer coefficient, directly. The paper describes the technique for manufacturing the tubes and gives results of systematic heat transfer measurements covering the effects of fin height, thickness, and spacing, tube diameter, and vapor velocity. The tests were carried out with steam, ethylene glycol, and R-113, with vertical vapor downflow. The heat flux was measured using an accurately calibrated 10-junction thermopile and paying particular attention to coolant mixing and isothermal immersion of thermocouple junctions. Care was taken to avoid errors due to the presence in the vapor of noncondensing gas and the occurrence of dropwise condensation. Smooth, consistent, and repeatable results were obtained in all cases. The data are presented in easily accessible form and are compared with the results of previous investigations, where indirect methods were used to determine the vapor-side data, and with theory.

Abstract:

The article deals with the issue of carbon dioxide adsorption on mineral samples, two of which are rich in montmorillonite and one in kaolinite. The last comparative sample is clinoptilolite, which is widely used as a sorbent in agriculture, water treatment, etc. The theoretical part summarizes several current researches on the use of bentonites as adsorbents, both in their raw form and after various chemical treatments. The study presented here does not suggest any modification procedure, but tests untreated samples and samples subjected to calcinations at temperatures of 250-750 ° C. The calcination of units of grams was carried out by means of a carousel TGA, which made it possible to record curves of mass changes and to obtain a sufficient amount of calcinates for further analyses at the same time. From the point of view of achieving the highest specific surface area and the total pore volume, the optimal calcination temperature for the phyllosilicate samples ranged from 250 to 450 °C. Natural zeolite, on the other hand, showed a deterioration of both of these parameters at any temperature exceeding 150 °C. The same temperature dependence was found in the case of adsorption capacities determined by an automatic analyser Autosorb IQ using pure CO2. Measurements on this instrument also confirmed that selected inexpensive natural materials provide comparable adsorption capacities as the commercially available 13X molecular sieve used as a reference sample. Based on the performed analyses, the initial conditions of sample preparation for the upcoming measurement of adsorption properties on a larger apparatus operating in the PSA/TSA mode were determined. The primary aim of the tests using the selfdesigned high-pressure adsorption unit will be to determine the adsorption capacities that will take into account the temperature and pressure conditions in a real postcombustion carbon dioxide capture system. Unlike the automatic analyser described above, it will be possible to quantify the influence of important factors such as: flue gas humidity, the presence of other permanent gases (especially SO2) and last but not least various CO2 partial pressures and absolute pressure during adsorption and desorption. The experiments will verify the extent to which the presence of noncondensing moisture in the gaseous mixture is problematic. In the case of phyllosilicates, it is not just the parallel adsorption of H2O that affects the adsorption capacity available for CO2 capture. It will be empirically determined to what extent the swelling of the sorbent occurs in the wet gas, changing the gas flow through the layer and especially the pressure loss. The results of measurements on high-pressure apparatus will be the basis for the design and construction of a larger pilot scale unit.
