Thermophoresis and Brownian diffusion of nanoparticles around a vertical cone in a porous media by Galerkin finite element method (GFEM)

In this study, Galerkin weighted residual Finite Element Method is used to find the thermophoresis and Brownian diffusion motion of two phase nanofluid flow around a vertical cone in porous media. Gravity, Drag, Thermophoresis and Brownian forces are confided on the nanoparticles to find their motio...
