Abstract

The aim of this study is to determine heat and mass transfer over a vertical plate in the presence of periodic suction and heat sink. The dimensionless governing equations are solved using perturbation technique. The velocity, temperature and concentration profiles are studied for different physical parameters like Suction parameter s, Heat sink F, thermal Grashof number Gr, mass Grashof number Gc, chemical reaction parameter K, Prandtl number Pr and Schmidt number Sc. It is observed that the velocity increases with increase in F and s. It is also observed that temperature increases with increasing F, Pr but s decreases with rise in temperature. While concentration increases with increasing Sc and K. the aim of the study is to determine the rate of heat and mass transfer of the system.
