Double-diffusive bioconvection effects on multi-slip peristaltic flow of Jeffrey nanofluid in an asymmetric channel
Due to the numerous uses of nanofluids in industry and nanotechnology, scientists and engineers have given special attention to the subject of nanofluid mechanics. In the realm of fluid mechanics, it is a considerably more interesting research topic. Motivated by its useful applications in the rheological modelling of many important liquids, we seek to demonstrate the Jeffrey nanofluid model. The intention is to show the effects of multi-slip boundary condition of peristaltic flow in an asymmetric channel in the presence of viscous dissipation and bioconvection. Double diffusive convective flow is saturated with Jeffrey nanofluid containing gyrotatic micro-organism. The dimensional governing equations are converted into non-dimensional forms by suitable dimensionless parameters. The analytical method has been used to obtain solutions for the non-dimensionless system. The impact of different physical characteristics on velocity, temperature, concentration, volume fraction and trapping phenomenon has been analysed through graphs. From the study, it is observed that the velocity slip parameter increases the velocity profile, whereas the velocity profile decreases in the case of bioconvection Rayleigh number, double-diffusive and nanofluid buoyancy ratio, and it is also noticed that the density of the motile micro-organism is lowered by the Peclet number and for bioconvection constant. The present study is useful in academic research, biomedicine and theoretical studies of hemodynamics, and also micro-organisms that are favourable in maintaining the ecosystem and human health. In a few cases, the current analysis shows a substantial agreement with previously published results.
