An IBM approach for the direct numerical simulation of convective heat transfer in particle-laden flows is proposed. An immersed boundary method (IBM) used in this research is body-force type, which has been developed by the authors. It can effectively deal with multiple moving boundaries and solve the temperature field not only of fluids outside solids but also inside solids. It is assumed that the fluid is incompressible and Newtonian, and buoyancy caused by density difference is calculated with the use of Boussinesq approximation. In calculating the heat flux between fluids and solids, its continuity is particularly considered. The applicability of this method is demonstrated through the simulation of simple two-phase flows.
