Boundary layer flow of Maxwell fluid in rotating frame with binary chemical reaction and activation energy

Abstract

Here we study the heat/mass transfer effects on revolving flow of Maxwell fluid due to unidirectional stretching surface. Mass transfer process is modeled in terms of binary chemical reaction and activation energy. Modified Arrhenius function for activation energy is invoked. Traditional boundary layer approximations are utilized to simplify the governing equations. Using similarity method, self-similar form of boundary layer equations are derived which are solved numerically. The solutions depend on dimensionless numbers such as the rotation parameter λ, the Deborah number β, the Prandtl number Pr, the Schmidt number Sc, activation energy E, fitted rate constant n and temperature difference parameter δ. We found that the solute concentration in binary mixture is proportional to both rotation parameter λ and activation energy E. The reaction rate σ and fitted rate n both provide reduction in the solute concentration. Thermal boundary layer becomes thicker and heat transfer rate diminishes when fluid is subjected to a larger rotation rate.
