Chemical Reaction Effects on Flow Past an Exponentially Accelerated Vertical Plate with Variable Temperature

Abstract

An analysis is performed to study the unsteady flow past an exponentially accelerated infinite vertical plate with variable temperature and uniform mass diffusion, in the presence of a homogeneous chemical reaction of first-order. The plate temperature is raised linearly with time and the concentration level near the plate is raised uniformly. The dimensionless governing equations are solved using the Laplace transform. The velocity profiles are studied for different physical parameters such as the chemical reaction parameter, thermal Grashof number, mass Grashof number, a, and time. It is observed that the velocity increases with increasing values of a or t. But the trend is just the reverse in the chemical reaction parameter.
