Bioconvection in radiative Glauert wall jet flow of nanofluid: a Buongiorno model

The wall jet flow is obtained by leading a free jet to flow in an area of a surface normally. In the presence of microorganisms, particularly gyrotactic-type organisms, the suspension becomes very efficient due to their capabilities and the dilution of nanoparticles in base liquids. The scientific community, particularly those working in the fields of biomedical devices, biomicrosystems and biotechnology, bioconvection has taken notice of these characteristics. Numerous industrial procedures encompass convection based on bioconvection and motile density. In the present study, a laminar Glauert wall jet flow in the presence of bioconvection, slip and suction is investigated by using the Buongiorno model. The governing equations that state the flow problem are converted into ordinary differential equations (ODEs) by applying Glauert transformations. The ODEs are solved numerically by applying fourth fifth order of Runge-Kutta-Fehlberg (RKF-45) scheme along with the shooting method. The noteworthy results of the current study are that the rise in values of Brownian motion, radiation, and thermophoresis parameters enhances the thermal profile. The increase in values of concentration difference and bioconvection Peclet numbers decays the microorganism profile. The rate of heat transfer declines for rise in values of thermophoresis parameter and inclines for higher values of radiation parameter.

Automated summary

This study investigates the laminar Glauert wall jet flow in the presence of bioconvection, slip and suction using the Buongiorno model. The results show that increasing values of Brownian motion, radiation, and thermophoresis parameters enhance the thermal profile, while increasing values of concentration difference and bioconvection Peclet numbers decay the microorganism profile. The rate of heat transfer decreases with increasing thermophoresis parameter and increases with higher radiation parameter.
