Entropy optimisation of a viscous bioconvective nanofluid flow with Coriolis and Lorentz forces using bivariate spectral quasi-linearisation technique

Abstract

This article carried out an investigation on the entropy optimisation and effects of Hall current followed by other key parameters on an electrically conducting rotational viscous nanofluid containing micro-organisms combined with different Biot numbers at the boundary layers. The governing mathematical model is converted into nonlinear coupled ordinary differential equations followed by boundary conditions using similarity transformation. Further, the obtained equations are numerically solved by the bivariate spectral quasi-linearisation method (BSQLM). The effect of key parameters has been analysed graphically. A decrease in the flow rate and an increase in both temperature and solute profiles are perceived, corresponding to thermal and solutal Biot numbers, respectively. Moreover, favourable outcomes are also observed for the generation of entropy for different Reynolds and Brinkman numbers.
