Magnetohydrodynamic viscoelastic boundary layer flow past a stretching plate and heat transfer

摘要

The heat transfer from a non-isothermal stretching sheet in the presence of a transverse magnetic field is analyzed using the theory of viscoelastic fluid formulated by Walters [Second Order Effects in Elasticity, Plasticity and Fluid Dynamics, Pergamon, 1964] and Beard and Walters [Proc. Cambridge Philol. Soc. 60 (1964)]. By means of the successive approximation, method the governing equations for momentum and energy have been solved. The effects of the coefficient of elastic velocity of fluid K0, surface mass transfer fω, Alfven velocity α, Prandtl number P, and relaxation time parameter τ0 on the velocity, and temperature have discussed. Numerical results are given and illustrated graphically for the problem considered.
