Heat transfer in unsteady separated stagnation point flow of a micro-polar fluid: Cattaneo-Christov model

In this study, the heat transfer is carried out for the stagnation point flow of micro-polar fluid for unsteady flow. To formulate an energy equation, Cattaneo-Christov heat flux model is applied despite formal Fourier's Law. The partial system of differential equations is transformed to coupled set of ordinary differential equations. The numerical results are obtained by invoking R - K integration procedure with shooting method. The flow carried to the separation region showed the attached flow phenomenon and reverse flow phenomenon depending upon the physical parameters involved in the study. An analysis is performed to show the effects of thermal relaxation time. Study shows that temperature profile declines for more sizably large values of relaxation time, while upsurges on incrementing Eckert number.

Automated summary

This study investigates heat transfer for the stagnation point flow of micro-polar fluid in unsteady flow, using the Cattaneo-Christov heat flux model and numerical integration procedures. The analysis shows the effects of thermal relaxation time on temperature profiles, which decrease for larger relaxation times and increase with increasing Eckert number.
