Numerical study of magnetized Powell–Eyring hybrid nanomaterial flow with variable heat transfer in the presence of artificial bacteria: Applications for tumor removal and cancer cell destruction

This investigation determined the effectiveness of an exterior magnetic field on bacteria enclosed by thousands magnetite nanoparticles. Variable thermal conductivity and Joule heating were used in interstitial nano liquid which artificial swimming a biotic cell. The unsteady motions Powell–Eyring fluid two dimensions assumed. porous extending wall was as bent surface shape. To convert governing non-linear PDEs into ODEs, suitable transformations exploited. homotopy analysis technique (HAM) utilized to resolve semi-analytical results ODEs. Plots investigate impact significant parameters velocity distribution, temperature profile, bacterial density field, nutrient concentration skin friction, Nusselt number, density. Clinical disease has shown that daring tumors have reduced blood flow. this study showed augmenting values improved profile. distribution decreased for higher volume fraction values, well porosity parameters. As nanoparticles increased, so did distribution. result, immersion physical characteristics blood. These findings also demonstrated Eckert number play essential role increasing heat transfer rates.
