ジャーナル フリーThe vapor-liquid equilibrium calculation for 34 binary systems containing hydrogen reveals that an extended BWR equation of state can be applied over a wide range of temperatures, 70-730 K, and pressures up to 25 MPa with temperature-dependent binary interaction parameters. The use of these parameters gave excellent predictions for the vapor-liquid equilibria of six ternary systems containing hydrogen.抄録全体を表示PDF形式でダウンロード (326K) -

ジャーナル フリーThe transition from bubbling to jetting at single holes was studied experimentally.
Transient jetting in addition to the six different regimes reported by Muller et al. was noticed. Empirical equations predicting the steady to pulsating and the pulsating to transient jetting transitions are obtained in terms of the dimensionless liquid depth, the modified Froude number and the Bond number, which have been proposed by Payne et al., and the state diagram showing the transition from bubbling to jetting is given by considering both the previous and the authors9 results at single orifices.抄録全体を表示PDF形式でダウンロード (391K) -

ジャーナル フリーLiquid-liquid extraction equilibria of mercury(II) by dicyclohexyl-24-crown-8 (C-24) in chloroform or xylene at 298 K were elucidated. The extraction equilibria are affected by the chloride ion concentration in the aqueous phase regardless of sodium chloride and hydrochloric acid concentrations. The formation constants of the extraction reaction expressed by the following equation
HgCl2 + C-24 →← HgCl2 C-24
were obtained at 7.0×102 dm3/mol for chloroform diluent and 1.9×103 dm3/mol for xylene diluent.抄録全体を表示PDF形式でダウンロード (308K) -

ジャーナル フリーMass transfer between two phases was studied in an agitated vessel with a flat liquid-liquid interface for 30 systems, where physical properties varied in a wide range. The observed Sherwood numbers for the first-phase Sh1 were correlated in terms of the first-phase Reynolds number Re1, modified second-phase Reynolds number Re2'', Schmidt number Sc1, Capillary number Ca1 and a function of viscosity ratio Φ. The correlation obtained represents all the data with an average deviation of 12.7%:

ジャーナル フリーA method for the calculation of effective pore size distribution from adsorption isotherms in molecular-sieve carbon is described. This method is more exact theoretically as well as practically than previously described methods. An average potential function has been determined inside the slit-like pores. With the help of this function the doubtful use of the Kelvin equation can be avoided at the scale of molecular dimensions. The method gives poor values for the larger pores but can be combined with the well-known Dollimore-Heal method at a pore size of 1.34 nm. Calculation is possible over a wide range of pore sizes. The calculation is shown through two examples from N2 isotherms at 77.4K. The model can be extended to other pore shapes as well as to other adsorbent-adsorbate pairs.抄録全体を表示PDF形式でダウンロード (404K) -

ジャーナル フリーStudies were made of axial dispersion in packed beds at low Reynolds numbers (0.01 to 1) using imperfect pulse chromatography. Three types of experiments were used to measure dispersion. One set was done with non-porous particles, another with non-porous particles coated with a thin liquid film to which mass transfer occurred, and a third set was done with porous particles in which there was internal diffusion.
Measurements confirmed the presence of a maximum Peclet number in the low Reynolds number region, as was previously identified by other workers. At the lowest Reynolds number used, the Peclet number approaches a limit imposed by molecular diffusion.
Different values of the axial dispersion coefficient were obtained in the presence of mass transport and internal diffusion. This disturbing result calls into question the validity of the commonly accepted dispersion-fluid particle transport model of packed beds in the region of low Reynolds numbers.抄録全体を表示PDF形式でダウンロード (548K) -

ジャーナル フリーExperiments were made using imperfect pulses at low Reynolds numbers to study mass transfer behaviour in packed beds. Two types of measurements were devised: those using non-porous particles coated with a thin liquid film of methyl silicone, and those using porous alumina particles. With the non-porous particles, a series of runs at Reynolds numbers ranging from about 0.025 to 0.25 gives conclusive evidence of a limiting Sherwood number of about 2. With the porous particles, mass transfer coefficients could not be measured. An effective diffusivity was measured, but its dependence on velocity in the bed at low Reynolds numbers suggests that the Kubin-Kucera model may be an inadequate description of the bed under these conditions.抄録全体を表示PDF形式でダウンロード (613K) -

ジャーナル フリーHeat transfer to pseudoplastic fluids was investigated in an agitated tank with helical ribbon impeller. A previous flow model developed for Newtonian fluids was extended for heat transfer in pseudoplastic fluids by the introduction of a simple model to evaluate the effects of fluid pseudoplasticity on axial velocity gradient at the wall. The extended model was shown to be effective in correlating heat transfer coefficients and in estimating temperature distributions in an agitated tank for both Newtonian and pseudoplastic fluids.抄録全体を表示PDF形式でダウンロード (424K) -

ジャーナル フリーThe high performance catalysts of hydrophobic carrier with fully dispersed platinum were used to measure the isotope separation performance of hydrogen by the chemical exchange method. The continuous injection of oxygen on the order of 103ppm was effective in regenerating catalyst activity and in maintaining high performance for a long time.
The separation performance in a trickle bed column should be evaluated by using two parameters, K9 and Kl. These two parameters were unified to the overall transfer coefficient Kfg, which may be sufficient in the estimation of overall performance or the design of a separation plant by the chemical exchange method.
When one wants to increase the transfer rate in a chemical exchange column, the improvement of Kl rather than Kg may be more effective in increasing the overall transfer rate (its coefficient is expressed by Kfg in this paper).抄録全体を表示PDF形式でダウンロード (603K) -

ジャーナル フリーThe initial stage of oil spreading on calm water was investigated for one-dimensional flow. Two kinds of experimental methods, instantaneous and constant rate of oil release, were used to investigate the rate of spreading and its dependence on surface contamination. Experimental and theoretical results were compared and some apparent discrepancies, hitherto unreported, are reported here. Also, a modified empirical correlation was obtained to express the spreading rate of oil slicks in the case of instantaneous oil release.抄録全体を表示PDF形式でダウンロード (462K) -
