Abstract

This paper deals with a theoretical study of laminar natural convection over a semi-infinite vertical plate. It is assumed that the plate is maintained at a given concentration in some chemical species and convection is induced by diffusion into and chemical reaction with the ambient fluid. The fluid is assumed to be viscous and the induced fluid flow, steady. A similarly transform to one variable is possible in the absence of chemical reaction. However, when the chemical reaction takes place between the plate and the ambient fluid, a similarity solution is not available. Thus to obtain an analytical solution of the problem, perturbation expansions about an additional similarity variable which is dependent on the reaction rate must be employed. It has been found
