Numerical and analytical comparisons of slanted Lorentz forces on thermal radiation flow of a micropolar fluid

The transient flow of a viscous incompressible electrically conducting microstretch fluid over an infinite vertical porous plate in the presence of slanted hydromagnetic flow with an aligned angle of to and thermal radiation effects has been analyzed. The governing equations are solved analytically by using the technique of the state space approach and the inversion of the Laplace transforms is carried out using a numerical approach for varies physical parameters on the velocity, microrotation, microstretch and temperature profiles are shown graphically. In order to verify the accuracy of the present results, we have compared these results with the numerical solution by using the Crank-Nicolson implicit finite difference method. It is found that the thickness of thermal boundary layer increases with an increase in the value of thermal radiation whereas antithesis trend is seen with increasing the Prandtl number.
