Onset of unsteady MHD micropolar nanofluid flow with entropy generation

ABSTRACT

We investigate the micropolar nanofluid model equations of MHD fluid in attendance of entropy generation on boundary layer over stretching surface and a chemical reaction to be significant. The heat and mass transfer are observed due to solutal and thermal stratification with thermal ration and viscous dissipation. The novel bivariate spectral quasiliearisation technique is employed to address the above mentioned mathematical model. Illustrating the different parameters are supported by requisite figures of their physical significance found in this method. The velocity of the thermal boundary layer is enhanced by increasing the local temperature Grashof number. The results perceived that entropy generation will enhanced for higher the Reynolds and Brinkman number, and thermal diffusion is the most dominant source of entropy generation.
