Influence of homogeneous/heterogeneous reactions on a radiative second-grade micropolar fluid flow over an exponentially stretching Riga plate with Joule heating

The main aim of current research work is to examine the impacts of homogeneous/heterogeneous reactions on the three-dimensional second-grade micropolar fluid flow caused by an exponentially stretching Riga plate. The thermal and solutal energy transportation characteristics are observed in the existence of Cattaneo-Christov heat flux, non-uniform heat source/sink and joule heating. Moreover, the features of thermal slip and porous medium are also incorporated in the mathematical model. The dimensionless process is adopted for the conversion of the PDEs into the self-similar form of ordinary differential equations (ODEs). The numerical approach Bvp4c is employed to solve ODEs and a comprehensive discussion is presented of arising physical parameters in this research work. The velocity profile rises as boosting the values of the microrotation parameter. Further, microrotation profiles along with x- and y-axes show decaying behaviour for the higher estimations of microrotation parameters. The homogeneous reaction profile has rising behaviour for higher values of Schmidt number and diminishing for higher estimations of strength homogeneous reaction parameter, respectively.

Automated summary

The research focuses on the effects of homogeneous/heterogeneous reactions on a specific fluid flow, using mathematical modeling and numerical methods to analyze the variations of velocity, microrotation, and reaction profiles under different physical parameters.
