Abstract

In this work, entropy generations of a variable viscosity Hartmann flow through a rotating channel with Hall effects are investigated numerically. It is assumed that the fluid and the channel rotate in agreement with the angular velocity about y-axis. The governing non-linear partial differential equations are transformed and solved numerically using Runge Kutta - Fehlberg method with shooting technique. Results obtained for velocities and temperature profiles are used to compute the entropy generation rate, skin friction and Nusselt number. The important results are displayed and discussed.
