Abstract

Abstract : Highlights: Mathematical modeling is conducted for unsteady bioconvection flow of chemically reactive Sutterby nanofluid for axisymmetric flow case. Bioconvection is considered. Nonlinear thermal radiation is accounted. Gyrotactic microorganisms is incorporated. Activation energy aspects are utilized. Abstract: Wide range of applications of Bioconvection with microorganisms and nanoparticles in the field of biotechnology, mechanical energy, biosensors, engineering and bioinformatics attracted the research community towards this field. Main objective of current communication is to present a mathematical modeling and numerical simulation for the unsteady Bioconvection flow of chemically reactive Sutterby nanofluid under the influences of gyrotactic microorganisms and nonlinear radiation. Additionally, activation energy influences are considered. Furthermore, we have adopted a newly developed revised nanofluid model to examine flow characteristics in nanofluid. Boundary layer theory is invoked to develop the basic PDEs for microorganism field, nanoparticles concentration, energy, momentum and mass and then reduced to the highly nonlinear ODEs with the help of transforming variables. Numerical solutions for current study are achieved via (RK45) shooting Fehlber approach. Numerical computations for density number of microorganism, Sherwood number, wall heat transfer and surface drag force are also conducted. For the authenticity of current study, a comparison analysis is performed between existing data and current study and revealed in excellent agreement. It is interesting to noticed that microorganism field is upgraded for higher estimation of microorganism difference parameter and Peclet number. It is also noted that larger Bioconvection Rayleigh number depreciates the fluid velocity.
