GPU accelerated lattice Boltzmann simulation of non-Newtonian power-law fluid in a porous enclosure

This paper demonstrates a numerical study of heat transfer in square porous cavity filled with non-Newtonian power-law fluid. A Graphics Processing Unit (GPU) has been used to accelerate the simulation, which uses Multiple-Relaxation-Time (MRT) Lattice Boltzmann Method. modified model employed characterize flow fluids. The simulations have conducted for index n ranging from (0.6 ≤ 1.0), Darcy number Da (10−3 10−1) and Raleigh Ra (103 105). Results show that average Nusselt (Nu) decreases an increase value while Nu increases Da. Moreover, increment leads number.
