Bioconvection effect in the Carreau nanofluid with Cattaneo–Christov heat flux using stagnation point flow in the entropy generation: Micromachines level study

Abstract The addition of gyrotactic microbes in the nanoparticles is essential to embellish thermal efficiency many systems such as microbial fuel cells, bacteria-powered micro-mixers, micro-volumes like microfluidics devices, enzyme biosensor, and chip-shaped microdevices bio-microsystems. This analysis investigates second law bioconvection flow a Carreau nanoliquid through convectively stretching surface. heat transports characteristics encountered with Cattaneo–Christove flux radiation. Buongiorno model used for nanoliquid, which comprises Brownian motion thermophoretic. appropriate transformation invoked change system partial differential equation into ordinary equations. Afterward, these equations are classified analytically help homotopy method. influence numerous physical variables interpreted elaborated via graphs. tabular result shows numerical consequences different parameters. It examined that more significant Weissenber number We {\rm{We}} results deprecation velocity field. appraised temperature profile reduces augment value relaxation time. Justification current work has existed previous publishing results. utilization shear rate-dependent viscous fluid importance due their potential improve mass transmission.
