Entropy optimized Darcy-Forchheimer flow of Reiner-Philippoff fluid with chemical reaction

Abstract

Here we simulate flow of Reiner-Philippoff fluid over a stretching sheet. Energy expression in the presence of heat generation, dissipation and thermal radiation is addressed. Entropy generation and energy communication is developed with the help of thermodynamic second and first laws. Thermodynamics second law states that irreversibility can be generated in any processes and not demolished in any system. Entropy generation is used to improve the system efficiency. Convection of a cooled or heated vertical plate/cone is one of the important problems in mass and heat transportation studies in current times. Physical features of first order chemical reaction are examined. Bejan number formulation is developed. Transformation procedure reduces partial differential system into ordinary system. Newton built in shooting method is used to construct computational outcomes. Prominence of influential variables on temperature, velocity, Bejan number, concentration and entropy optimization are graphically studied. Nusselt and Sherwood numbers are numerically computed against pertinent variables through tables. For higher approximation of Bingham number the velocity and temperature are augmented. Velocity is enhanced against Reiner Philippoff fluid parameter whereas opposite response is noticed for temperature. Temperature boosts up against higher estimation of Eckert number. Bejan number and entropy rate are increased for higher Bingham number and radiation parameter.
