Abstract:
This article presents the impact of inclined magnetic field on bioconvection of viscoelastic Casson nanofluid flow over a stretching sheet. A non-Newtonian nanofluid boundary flow over a horizontal surface suspension of gyrotactic microorganism is considered. It is assumed that the presence of nanoparticles will not disturb the direction of swimming and velocity of the microorganism. Also, the shape of the microorganism is assumed to be uniform and no production of extracellular polymer on the surface of the microorganism. The significant physical quantities namely skin friction, local Nusselt number, the local Sherwood number and the local density of the motile microorganism are evaluated. The mathematical equations are solved using the spectral local linearization method. Analysis of the accuracy and convergence properties of the method are also evaluated. The influence of certain variables on the fluid properties are discussed and displayed tabular and graphically.
