Thermosolutal Marangoni Impact on Bioconvection in Suspension of Gyrotactic Microorganisms Over an Inclined Stretching Sheet

Abstract

Microorganism cells movement in fluid is universal and affects many ecological and biological processes, including infection, reproduction and marine life ecosystem. There are many biological and medical applications that require understanding of transport process in nanofluids containing suspension of microorganism. The present problem deals with the bioconvection of Casson nanofluid containing suspension of motile gyrotactic microorganisms over inclined stretching sheet in the presence of thermal radiation, viscous dissipation, and chemical reaction and magnetic field. At the surface, influence of the thermo-solutal Marangoni convection and suction / injection impact are considered. The governing equations are solved numerically by using fourth order Runge-Kutta method with shooting technique. Impact of the major pertinent parameters on the velocity, temperature, nanoparticles concentration and density of the motile microorganism is illustrated graphically. Finally, correlation of various crucial parameters on skin friction, local Nusselt number, Sherwood number and local motile microorganism density number are displayed through graphs and tables.
