Dynamics of gyrotactic microorganisms for chemically reactive magnetized 3D Sutterby nanofluid flow comprising non-uniform heat sink-source aspects

This presents a theoretical and computational evaluation of the unsteady 3D Bioconvection flow of Sutterby fluid, which has non-linear nonlinear radiation features as well as gyrotactic microorganisms, illuminating novelty of the work. Furthermore, the influences of magnetic field, activation energy, chemical reactions, mixed convection and non-uniform heat sink-source are likewise indebted. Boundary layer theory is entreated progress the elementary PDEs designed for microorganism field, momentum, nanoparticles concentration and energy also then condensed to the extremely nonlinear ODEs through the variable's transformation. Numerical solutions for the existing investigation are obtained by bvp4c method in MATLAB software. Numerical calcu-lations intended for Sherwood number, density number of microorganism and wall heat transfer are corre-spondingly accompanied. The graphic illustrations for exemplifying features of diverse embryonic parameters dimensionless measures are designated systematically. It is fascinating to observed that the concentration as well as microorganism field is progressed for developed approximations of the bioconvection Rayleigh number and the magnetic parameter. The temperature of the fluid develops as a implied reaction to the magnetic parameter, the radiation parameter, Biot number and temperature ratio parameter.
