Entropy optimized flow of Darcy-Forchheimer viscous fluid with cubic autocatalysis chemical reactions

Abstract

The dynamic of entropy generation phenomenon is important in industrial and engineering process and thermal polymer processing. In order to improve the thermal efficiency of industrial and systems, the main concern of scientists is to reduce the entropy generation. The optimized frame for the Darcy-Forchheimer flow accounted by curved surface has been worked out this continuation. The applications of the chemically reactive material are focused via heterogeneous and homogeneous chemical utilizations. The thermal and velocity slip constraints are imposed for investigating the flow phenomenon. Additionally, the determination of heating phenomenon is investigated by incorporating the heat source features. The importance of entropy generation and Bejan number is also signified. Nonlinear partial systems are reduced to dimensionless differential system through suitable variables. The problem consists of highly nonlinear equations are numerically worked out with appliances of ND-solve procedure. Influence of fluid flow, thermal field, entropy rate, concentration and Bejan number via influential variables are examined. A slower velocity change due to implementation of slip is noticed. The applications of Brinkman number offer resistance to fluid particles while an enhancement in the Bejan number is claimed. For an augmentation in curvature variable, the concentration and velocity show reverse effect. There is an increase in temperature distribution against heat generation parameter. Velocity field is reduced against higher porosity and slip parameters. Temperature has revers trends against radiation and thermal slip parameters. Larger Schmidt number decreases concentration distribution. Entropy rate is augmented versus larger radiation parameters. An augmentation in Brinkman number leads to improve the velocity filed whereas it reduces the Bejan number. Brinkman number influence on Bejan number is similar to that of homogenous reaction parameter on concentration. The comparative simulations against the reported results are performed. • Entropy optimized Darcy-Forchheimer flow over a curved stretchable surface. • Energy expression is modeled by the implementation of thermodynamics first law. • Entropy generation is modeled through thermodynamic second law. • Thermal radiation, heat source/sink and dissipation is accounted. • Cubic autocatalysis chemical reactions are addressed.
