“…The sample volume was determined from its mass and density. The Benedict–Webb–Rubin (BWR) equation of state5 was used to calculate the mass of gas in the headspace at any time: where P , T , and ν are the pressure, temperature, and molar volume of the gas, respectively. The parameters a , b , c , A 0 , B 0 , C 0 , α, and γ are empirical constants found from the correlation of pressure–volume–temperature data.…”

ABSTRACT:In creating thin films of polymers by solution processing, a common problem is the undesirable formation of bubbles during the drying process. Practical experience shows that bubbles can be created well below the boiling point of the solvent. Also, it has been observed that the degassing of the polymer solutions results in reduced bubble formation, and this indicates a relationship between the presence of air and bubble formation. This work is based on the hypothesis that if the solubility of air in the polymer solution increases with the solvent concentration, then the solution can become supersaturated with air as the concentration of the solvent is reduced during the drying process. To test this hypothesis, knowledge of the thermodynamics of the mixture is required. This study concentrated on the system of poly(vinyl acetate), toluene, and nitrogen. A thermodynamic model to predict phase behavior of this system was developed. The solubility of nitrogen in poly(vinyl acetate) and poly(vinyl acetate)-toluene as a function of the toluene composition over wide ranges of temperatures and pressures was measured with the pressure decay technique. The group-contribution lattice-fluid equation of state was employed to correlate the thermodynamic behavior of the binary and ternary systems. In addition, experiments were conducted to measure the diffusion coefficients of the nitrogen in poly(vinyl acetate).

“…An expression for the enthalpy of a mixture of components is obtained by first carrying out the differentiation implied by eq 12 with the aid of eq 13. Then the constants for the pure component in the expression so obtained are replaced by the constants for the mixture (Orye, 1969;Reid and Sherwood, 1958). The result so obtained may be represented as follows…”

An upwind finite-difference representation of the vorticity-stream function formulation of the full Navier-Stokes and energy equations was used to predict the flow and local heat transfer characteristics of a laminar semi-confined round jet impinging normally on a stationary plane wall. Effects of Reynolds number, distance between jet nozzle and impingement surface, diameter of the impingement and confinement surfaces, shape of the velocity profile at the nozzle exit, and application of uniform suction at the impingement plate were studied numerically. Favorable agreement between predicted heat transfer rates and published data was obtained for those few cases for which experimental data were available. The velocity profile at the nozzle exit was found to be a particularly important variable while the application of suction was found to enhance the heat transfer rates significantly.
