Significance of Cattaneo-Christov Heat Flux on Heat Transfer with Bioconvection and Swimming Micro Organisms in Magnetized Flow of Magnetite and Silver Nanoparticles Dispersed in Prandtl Fluid

Hybrid nanofluids are utilized in vast applications in heat transfer such as heat exchangers, solar trough collectors, and in fields, namely aerospace engineering, material science, and food processing. Hybrid nanofluids possess far higher thermal conductivity as compared to convectional fluids; keeping in view this feature, this study is conducted to investigate the impact of notable Prandtl hybrid nanofluid using mixture base working fluid on thermal characteristics of bioconvective flow. To further elaborate the thermal attributes of bioconvective flow, the Cattaneo-Christov heat flux (CCHF) model has been taken into consideration in the present formulation. The focus in this investigation is to examine the impact of Cattaneo-Christov heat flux (CCHF) in the presence of bioconvection and microorganism effects on the mixture-based Prandtl hybrid nanofluid over heated stretched surface. To develop the desired fluid model, the Prandtl fluid model has been taken into account. In this work, silver and magnetite nanoparticles have been incorporated to constitute our desired Prandtl hybrid nanofluid, whereas the base fluid comprises mixture of ethylene glycol/water (50%-50%). The developed mathematical model is highly nonlinear, so we have computationally solved it using the bvp-4c technique. It has been discovered that when thermal relaxation levels are kept in the range of 0.5 to 0.9, the temperature profile significantly improves consequently enhancing heat transfer coefficient over the heated surface. It has been found out that as the levels of bioconvection enhance, migration of motile microorganism declines abruptly, causing the reduction in fluid acceleration. Additionally, with constant magnetization and varying inclination angle, the momentum layer thickness has been observed to expand. Heat transfer coefficient rises by raising the values of magnetization, Rayleigh bioconvection number, and thermal relaxation number. Moreover, results achieved in this present study have been verified through comparison with already published results, and good agreement has been found.
