Abstract Current work focuses on increasing heat transmission in thermal systems with the incorporation of gyrotactic motile microbes, promoting creation structured fluids useful for bio-cooling and nanotechnology. This study explores effects electroosmosis slip boundary conditions a non-Newtonian Casson nanofluid mass transfer. Specifically, it looks at bio-convection peristaltic events conducts thermodynamic analysis. The Arrhenius activation energy an asymmetric channel is considered this study. In addition, authors evaluate viscous resistance, thermophoresis diffusion, porous surface properties, coupled convection, Brownian viscosity behavior. results obtained from mathematical expressions together are handled by means numerical algorithm implemented shooting technique through traditional program Mathematica, aid its built-in tool, NDSolve. Many physical parameters, such as entropy generation, Bejan number, velocity profiles, density accumulation profile nanoparticles, depicted graphically. graphical shows that generation increases greater Helmholtz-Smoluchowski factor 10%, but declines generation/absorption same percentage. number tends to increase stronger sources 5%. Application possibilities include improved control effectiveness mechanisms microfluidic equipment, delivering medications, biotechnological operations.
