ABSTRACT

The paper focuses on first and second law analyses for flow and heat transfer inside a uniformly porous vertical pipe. The pipe flow is subjected to a constant suction at the wall and is acted upon by a combination of buoyancy forces, a transverse magnetic field, and constant pressure gradient. The pipe walls are kept isothermal and the flow of the conducting fluid is assumed to be unsteady with variable viscosity. The nonlinear governing equations in cylindrical coordinates are obtained under axisymmetric assumptions and solved numerically using semi-implicit finite difference techniques to obtain expressions for the velocity and temperature profiles. The entropy generation number, irreversibility distribution ratio, and Bejan number are presented graphically and discussed quantitatively for various values of the embedded parameters.
