“…The fluid flow and heat transfer processes are basically irreversible, which results to an increase entropy production and beneficial energy destruction. Entropy generation has stirred substantial attraction of many researchers recently such as [1][2][3]. Guillermo [4] studied the global entropy generation in steady flow of an incompressible electrically conducting fluid through a channel with permeable plates putting in consideration some parameters such as hydrodynamic slip, magnetic field, suction/injection and convective boundary conditions.…”

We investigate entropy production rate in a temperature dependent viscosity Hartmann flow with Hall current through a rotating permeable channel. It is assumed that fluid suction occurs at the upper wall and injection at lower wall. The nonlinear governing differential equations are obtained, analyzed and solved numerically using shooting technique together with Runge-Kutta-Fehlberg integration method. Velocity and temperature profiles obtained from the numerical solutions are then used to compute the skin frictions, Nusselt number, the entropy generation rate and the Bejan number. The germane results are presented and discussed quantitatively.
