Unsteady Thermal Diffusion Effects on MHD Free Convection Flow of a Nanofluid Containing Gyrotactic Microorganisms Past a Vertical Plate

This work qualitatively investigates the unsteady thermal diffusion effects on MHD free convection flow of a nanofluid containing gyrotactic microorganisms past a vertical plate. The interaction of a magnetic field with nanoparticles and microorganisms on a vertical plate is examined and analysed. Designing the model using a geometrical layout, the fundamental equations are transformed into dimensionless form by the use of appropriate non-dimensional variables. The derived non-similar reduced differential equations were resolved using the explicit finite difference approach with the assistance of Studio Developer Fortran (SDF) 6.6a. Stability analysis as well as convergence criteria are examined to derive the convergent solutions. The effects of several parameters, including Grashoff number, Modified Grashoff number, Magnetic parameter, Prandtl number, Brownian motion parameter, Thermophoresis parameter, Lewis number, Soret number, Micro-organism Lewis number, Peclet number, suction parameter and Bio-convection parameter on the flow are examined, with the results illustrated graphically through physical representation. Ultimately, the present results are compared with the existing published findings.
