Numerical analysis of forced convection heat transfer in a rectangular micro-channel totally filled with Ag/ water nano fluid in slip flow regime using the lattice Boltzmann method

Numerical simulation reported on heat transfer and fluid flow in a two-dimensional rectangular micro channel totally filled with Ag/water. The first –order slip/jump boundary conditions were uniformly imposed to the up bottom walls. governing conservation equations are translated dimensionless form using thermal Single Relaxation Time (T-SRT) modified Lattice Boltzmann Method (LBM) double distribution functions (DDFs). viscous dissipations effects adopted into energy equation. Effects of nanoparticle volume fraction φ, slip coefficient, B, Nano studied. results interpreter terms velocity; temperature jump Nusselt number. Based found, it can be concluded that decreasing values coefficient enhances convective consequently number (Nu) but increases velocity at wall values.
