Abstract
The main objective of the paper is to explore the effects of Soret and Dufour on MHD mixed bioconvection of nanofluid in a flat channel with chemical reaction, radiation, Joule heating and partial (velocity) slip. The related ordinary differential equations are comprised of velocity, energy, nanoparticle concentration, solutal concentration and microorganisms density are solved analytically subject to physically appropriate boundary conditions using homotopy analysis method (HAM). The dimensionless skin friction, heat and mass transport are discussed through plots by varying different physical parameters. The transport of heat enhances with Brinkman number but it increases gradually with thermal radiation. The fluid velocity reduces by the velocity slip, while it increases by raising the Hartmann number. The temperature of the fluid lowered due to the surplus thermal radiation. The dufour number and velocity slip create opposite effect in solutal concentration.
