Abstract


We examine the behavior of Cattaneo--Christov heat flux model for two-dimensional incompressible flow of Eyring Powell fluid passed over an exponentially stretching sheet. Mathematical formulation is performed by assuming boundary layer approximation. Cattaneo Christov heat flux model is applied to analyze the heat transport phenomenon. Thermal relaxation time is envisaged on the layer induced due to boundary. The governing Partial Differential equations are converted into Ordinary differential equations by the appropriate use of similarity transformation. Shooting approach is used to tackle the obtained boundary layer equations. The effects of obtained similarity parameters are plotted and discussed. Computation results reveal that fluid temperature is directly related with thermal relaxation. The comparison of results, in present situation, between Fourier's law of heat conduction and Cattaneo Christov heat flux model show that the temperature and the boundary layer (thermal) thickness are smaller in Cattaneo Christov model.
