Forced-Convection Condensation of Multicomponent Vapors
Toorl and Stewart and Prober2 derived the boundary layer equations for a multicomponent vapor mixture by linearizing the relevant diffusion coefficient. They then transformed the equations to the same form as those in a binary vapor mixture by using a matrix method. Toor discussed that the solution for forced-convection mass transfer of a binary vapor mixture can be extended to the case of the multicomponent mixture. Stewart and Prober obtained a solution for forced-convection condensation of a hydrogen-nitrogen-carbon dioxide mixture by combining the matrix method and stagnant film theory, and showed that the agreement between the result and corresponding solution of the boundary layer equation is good. Fujii and Koyama3 proposed an algebraic method for solving the condensation problem of a ternary vapor mixture, which is derived by a matrix transformation of ordinary differential equations using the result of a binary vapor mixture case. Koyama et al.4 successfully extended this method to a multicomponent condensation problem.
