Abstract:
The goal of this thesis to investigate the consequence of thermal stratification, thermal radiation, heat source/sink, the gyrotactic microbes in the nanofluid is important to enhance the thermal proficiency of various systems like bacteria live micro-mixers, microbial fuel cells, micro volumes such as enzymatic biosensor, microfluid flow devices, and chip shaped microdevices as bio-micro systems. In addition, the motivating research area in the current era is the suspension of nanoparticles with microorganisms which plays a vital role in the field of biotechnology and biomedical implementations. With this motivation, the purpose of this examination is to give an analysis of gyrotactic microbes bioconvection occurrence for the flow of Reiner-Philippoff (R-P) nanofluid in presence of thermal radiation and heat source-sink within a non-uniform thickness over a stretching surface. The governing equations are partial differential equations which are transformed into a coupled system of nonlinear dimensionless equations. The dimensionless equations are then tackled by a numerical technique (shooting method) using computational MATLAB scheme. The influences of the flow parameters on the velocity, mass and heat transfer rates, motile microbe rate of diffusion is analyzed and demonstrated via graphs and tables. Numerical findings concluded that the bioconvection Peclet number and motile microbe increase the motile microorganism’s concentration. Furthermore, the thermal radiation increases the temperature
