Physical attributes of bio-convection in nanofluid flow through a paraboloid of revolution on horizontal surface with motile microorganisms

Abstract

Nanofluids are unique functional fluids some of which are designed to reduce power losses while boosting thermal resistance. The subatomic particle thermophoresis and Brownian motion are necessary components in heat conduction in these fluids. This report describes the characteristics of bio-convection aspects of Casson nano fluid incorporated with thermal radiation with activation energy beyond a horizontal paraboloid region. Several studies examined the blood flow in the circulatory system employing non-Newtonian fluid models. The influence of prominent parameters, like Brownian diffusion and thermophoresis effects with bioconvection Lewis numbers are used. The coupled nonlinear governing PDEs are supposed to be transformed into nonlinear ODEs via similarity transformation. The obtained highly non-linear ODEs are tackled with shooting scheme, the solution of transformed equations is numerically obtained using ‘bvp4c,’ a MATLAB technique, to examine the problem. A schematic diagram is extensively employed to really see the influence of different effective factors. Graphical as well as numerical results against the velocity, temperature, concentration, and, motile microorganism profiles. As noticed that the findings, although the velocity profile decline as mounting values of magnetic parameter and upshot as small increment in the value of mixed convection parameter. In supporting flow circumstances, temperature profile overshoot is noticed, as small amount of radiation parameter. Biot number is increased in local Nusselt number and motile microorganisms. The results are computed in different ways like figures, tables and bar charts. The efficiency is observed for different values of various parameters.
