Multicomponent mass transfer in turbulent flow

Abstract

A general treatment of entry region multicomponent mass transfer between a fully developed turbulent flow and a smooth pipe wall has been developed from a basis first derived by Toor.The coupled multicomponent equations were reduced to a n equivalent binary system by the method of undetermined constants. Numerical solutions for a forced convection, binary diffusion system involving gas-phase, nonequimolal diffusion were opplied to a ternary system. These solutions have been found to compare well with these authors entry region mass transfer data on a ternary acetone-methanol-air mixture and with the earlier analogy theories derived for the case of a n infinitely long test section. W e conclude that there is a significant interaction in some multicomponent systems, enough that the binary theory can not be satisfactorily applied in the design of multicomponent mass transfer systems. diffusion which can be described by the equation

Perpindahan Panas Dan Massa Pada Pengembunan Campuran Metanol-Propanol-Udara Dalam Kondensor Tegak

“…Pengembangannya terletak pada mekanisme perpindahan massanya yang dapat dikelompokkan menjadi 3, yaitu Model Difusivitas Efektif (Schrodt, 1973), Model Linear (Toor, 1964), dan Model Interaksi (Krishna and Panchal, 1977;Burghardt and Berezowski, 1992;Mazzarotta and Sebastian, 1995). Interaksi antara senyawa yang mendifusi dalam campuran multikomponen sangat berperan dalam perancangan sistem perpindahan massa multikomponen (Behren et al, 1972).…”
