This paper is concerned with the entropy generation in a magnetohydrodynamic (MHD) pseudo-plastic nanofluid flow through a porous channel with convective heating. Three different types of nanoparticles, namely copper, aluminum oxide and titanium dioxide are considered with pseudo-plastic carboxymethyl cellulose (CMC)-water used as base fluids. The governing equations are solved numerically by shooting technique coupled with Runge-Kutta scheme. The effects of the pertinent parameters on the fluid velocity, temperature, entropy generation, Bejan number as well as the shear stresses at the channel walls are presented graphically and analyzed in detail. It is possible to determine optimum values of magnetic parameter, power-law index, Eckert number and Boit number which lead to a minimum entropy generation rate. ª 2015 Production and hosting by Elsevier B.V. on behalf of Faculty of Engineering, Alexandria University.

“…Aziz and Khan [21] analyzed the entropy production of steady conduction in the model of a hollow sphere with temperature-dependent internal heating and asymmetric convective cooling boundaries. Malvandi et al [22] studied the entropy production of steady two-dimensional boundary layer flow of nano-fluids over a flat plate. Torabi and Zhang [23] used classical entropy production analysis to investigate heat transfer in cooled homogenous and functionally graded material slabs with variation of internal heat generation with temperature, and convective-radiative boundaries.…”

Abstract:Response Surface Methodology (RSM) is introduced to optimize the control rod positions in a pressurized water reactor (PWR) core. The widely used 3D-IAEA benchmark problem is selected as the typical PWR core and the neutron flux field is solved. Besides, some additional thermal parameters are assumed to obtain the temperature distribution. Then the total and local entropy production is calculated to evaluate the energy dissipation. Using RSM, three directions of optimization are taken, which aim to determine the minimum of power peak factor Pmax, peak temperature Tmax and total entropy production Stot. These parameters reflect the safety and energy dissipation in the core. Finally, an optimization scheme was obtained, which reduced Pmax, Tmax and Stot by 23%, 8.7% and 16%, respectively. The optimization results are satisfactory.
