Thermal Effect on the Bioconvection Dynamics of Gravitactic Microorganisms in a Rectangular Cavity

In this work, the dynamics of bioconvection process gravitactic microorganisms enclosed in a rectangular cavity, is analyzed. The dimensionless cell and energy conservation equations are coupled with vorticity-stream function formulation. Then, effects Rayleigh number heating source on discussed. results based streamlines, concentration temperature contours obtained through numerical simulations considering eight different configurations symmetrical asymmetrical heat sources. It concluded that accumulate warmer regions swim cooler to reach surface. They form cells for each source, but at high concentrations, they single stable cell. presented here can be applied control understand discrete
