A general approximation solution for the mass transfer in laminar multicomponent boundary layers along a streaming plate plane
Abstract
Two formulations for the analogy defect of binary systems are presented in which the dependence of the Schmidt number is empirically introduced in the principles of film theory and frictionless flow. The plate-parallel convection with a linearly increasing flow profile was taken into account. The mass transfer was considered independently of the heat transfer. The flow was described by the continuity and Navier-Stokes equations and the diffusion effects were expressed by the Fick law through the mass concentration gradients. The mass transfer was calculated from binary, equimolar systems and for ternary systems such as methanol-helium, water-helium, acetone-benzole-helium and isopropanol-water-nitrogen. A method for the estimation of reference values of mass density and dynamic viscosity mixtures with components whose molar masses are significantly different is presented.
