Abstract Impact of gyrotactic microorganisms on two-dimensional (2D) stratified flow of an Oldroyd-B nanomaterial is highlighted. Applied magnetic field along with mixed convection is considered in the formulation. Theory of microorganisms is utilized just to stabilize the suspended nanoparticles through bioconvection induced by combined effects of ...

AbstractMarangoni bio‐thermal convection in a layer of nanofluid with gyrotactic microorganisms is investigated. The motion of the nanoparticles is characterized by the effects of thermophoresis and Brownian diffusion. The lower boundary of the nanofluid layer is assumed to be a rigid surface at constant temperature and the upper boundary is assumed to

Impact of vertical vibration and gyrotactic microorganisms on stability of thermo-bioconvection
Mechanics Research Communications, 2021Abstract By using vertical vibration of high frequency, the stability of dilute suspension containing gyrotactic microorganisms in a horizontal layer of finite depth heated from below is investigated. A time-averaged method and linear stability analysis are used to obtain the governing equations describing the mean flow of the suspension.

Stability of Bioconvection in Suspensions of Gyrotactic Microorganisms in Porous Media
Heat Transfer, Volume 7, 2002In this paper, a model of bioconvection in a suspension of gyrotactic motile microorganisms in a fluid saturated porous medium is suggested. The microorganisms considered in this paper are heavier than water and gyrotactic behavior results in their swimming towards the regions of most rapid downflow.
