Multiple slip effects on bioconvection of nanofluid flow containing gyrotactic microorganisms and nanoparticles

Abstract

In the present paper we attempt to formulate the equation of motion for bio convective flow of nanofluid containing gyrotactic microorganisms past a vertical stretching sheet. In the model we incorporate the multiple slip conditions at the boundary surface. Then by introducing a similarity transform we convert the governing boundary layer equations into nonlinear ordinary differential equations coupled with appropriate boundary conditions and solve it numerically by using Maple 17 software. The effects of different slip parameters on flow characteristics are surveyed through proper graphs and charts. After analysis it is found that slip parameters are highly correlated with various physical properties of the flow field. Also from numerically compute data it is detected that growth in nanoparticle density slip parameter consequences 23.64% shrinkage in mass transfer proportion and 10.11% decline in microorganism density number and alternatively heat movement speed lessened by 11.16% with the institution of temperature slip effect in the stream.
