Effect of finite normal interfacial velocity on free convection heat and mass transfer rates from an inclined plate

Abstract

An analytical study has been carried to examine the effects of finite normal interfacial velocity on simultaneous heat and mass transfer rates in a laminar, free convection binary boundary layer along an inclined plate. The plate is maintained at uniform temperature and/or concentration. Analyses cover the range of Schmidt numbers, .22–5.0, which represent the diffusion of commonly occuring and technologically important gases and vapors in air. Numerical results are presented in tabular forms for better comparision. The study have revealed that in case of simultaneous transfer the increase in interfacial velocity substantially decreases the rate of heat transfer, specially in case of diffusion of species of low Schmidt numbers. Mass transfer rate both incase of pure and combined transfer also decreases with the increase of the normal interfacial velocities.
