摘要:

AbstractAn experimental study in the behavior of nitrogen and neon pool boiling was performed. The test section consisted of a vertical pipe 3 in. O.D. × 7½ in. long. The variables studied are: heat input, submergence, and surface finish. Several copper heaters were tested, in addition to nickel and cadmium plated heaters. The results were correlated for nitrogen by an equation which gave an average deviation of ± 16% for all the heaters except the cadmium plated heater. The paper describes the experimental equipment and technique, summarizes the data, and compares them to literature values and equatio

摘要:

AbstractThe object of this paper, first in the series dealing with the generalized thermodynamic properties of real gases, is to present generalized compressibility charts in the reduced temperature range of 1.0 to 15.0 and a reduced pressure range of 0 to 40.0. A detailed summary of deviations of the present charts with PVT values of different gases is presented. A summary of the comparison of the present charts with the existing charts is also given.

摘要:

AbstractBy use of a least‐squares technique, a set of parameters for the generalized Benedict‐Webb‐Rubin equation is determined. The generalization of the equation is based on the modified theorem of corresponding states. The generalized equation shows a grand average absolute deviation of 1.6% in predicting the observed values of reduced pressure. The set of constants has been determined for densities up to twice the critical density in the reduced pressure range of 0 to 40.0 and a reduced temperature range of 1.0 to 15.0. The recommended generalized constants are Ao′ = 0.24180980, ao′ = 0.04407059 a′ α′ = 0.11369478 × 10−3, Bo′ = 0.07643101, b′ = 0.03715171, Co′ = 0.21217005, c′ =

摘要:

AbstractA finite difference technique is used to calculate the velocity profile, maximum shear stress, and friction factor‐Reynolds number product for a power‐law, pseudoplastic fluid flowing through a cylindrical duct of rectangular cross section. It is assumed that the motion is rectilinear. A very simple friction factor‐Reynolds number correlation is obtained for the special case of a square

摘要:

AbstractThe friction factor and Reynolds number were measured for sodium carboxymethylcellulose (cmc) flowing through a rectangular duct. Measured values were compared with values calculated in Part I of this paper. Both a pipe viscometer and a Couette viscometer were used to evaluate the rheological parameters for the fluids. Calculations were based on a power law model. The agreement between theoretical and experimental values was excellent.

摘要:

AbstractRadial mixing of concentrated solutions of rubber dissolved in a light aliphatic hydrocarbon was studied in beds packed with glass spheres or York mats. The degree of mixing in the bed of spheres was significantly better, that is the Peclet number much smaller, than predicted from Wilhelm's correlation.Pressure drop associated with the flow of rubber cement through packed beds is well represented by existing correlations, provided the effective viscosity is obtained from a shear rate vs. shear stress diagram for the fluid.

摘要:

AbstractMixing and a rapid, second‐order irreversible chemical reaction were studied in a turbulent chemical flow reactor, with a point conductivity probe used to detect changes in concentration. From the mathematical theory of Toor, it is shown experimentally that data on the mixing of a passive scalar additive in a nonreactive system may be used accurately to predict the yield of a rapid, irreversible second‐order reaction when the hydrodynamics and initial conditions on mixing for the reactive system are identical to those of the nonreactive system. Increasing the bulk average concentration of one reactant is shown to have a strong effect on the overall reaction yi

摘要:

AbstractPseudocritical rules provide a means to determine reduced properties for mixtures so that pure component corresponding states correlations may be used to estimate mixture properties. The most common pseudocritical rules are examined and shown to stem from a common base. Points of divergence as well as similarity are pointed out in tracing out the development of the rules. Reduction of all rules to simpler forms is made and criteria attached to allow one to determine when such simplifications are justifiable. All rules reduce to Kay's rule in certain limiting cases.
