摘要：

This study uses the lattice Boltzmann method to research the heat transfer features of Pseudoplastic fluid in a microchannel. The Power law model is intended to simulate non-Newtonian fluids. The fluid slip on the surface is applied to the hydrophobic surfaces, and also the viscose dissipation term is considered in the governing equations. The problem is presented for Reynolds numbers 20 and 30, slip coefficients 0.01, 0.02, and 0.03, and Prandtl numbers 1 and 6.2. Results reveal that the average Nusselt number in the microchannel with a power index of 0.5 of non-Newtonian fluid is more significant than Newtonian fluid. It was seen that viscose dissipation impact on the average Nusselt number is insignificant.
