LBM parallel computation for flow and heat transfer of nanofluids

Based on lattice Boltzmann method (LBM), a lattice Boltzmann model is proposed for simulating flow and energy transport process of the nanofluid. Because of the intrinsic parallel characteristic of LBM, the parallel computation of the LBM simulation of nanofluid is carried out by means of message passing interface (MPI) approach. The optimal region-decomposed scheme and the processor number are discussed. The results show that the random motion of the suspended nanoparticles enhances heat transfer process of the base fluid. LBM is an appropriate approach to handle flow and energy transport problems of the nanofluid. The high efficiency parallel computation scheme of LBM has been achieved.
