A lattice Boltzmann algorithm for fluid-solid conjugate heat transfer

A lattice Boltzmann algorithm for fluid-solid conjugate heat transfer is developed. A new generalized heat generation implement is presented and a “half lattice division” treatment for the fluid-solid interaction and energy transport is proposed, which insures the temperature and heat flux continuities at the interface. The new scheme agrees well with the classical CFD method for predictions of flow and heat transfer in a heated thick-wall microchannel with less mesh number and less computational costs.
