On entropy generation effectiveness in flow of power law fluid with cubic autocatalytic chemical reaction

Here, cubic autocatalysis in radiative flow of power law fluid is addressed. Flow is examined by a stretched surface. Heat generation/absorption, nonlinear radiation and dissipation effect are utilized in modeling of energy equation. Through implementation of second thermodynamics law, the entropy rate is calculated. Further entropy generation is explored with respect to homogeneous and heterogeneous mass concentrations. Nonlinear system is tackled via NDSolve of MATHEMATICA. Impacts of pertinent variables associated with flow are physically discussed for the velocity, entropy generation, temperature and concentration fields. Clearly, entropy augmentation rate is controlled through Brinkman number. Main key points are presented.
