Lattice Boltzmann method (LBM) and direct simulation Monte Carlo (DSMC) method are used for analysis of moderate Knudsen number phenomena. Simulation results are presented for pressure driven isothermal microchannel flow at various pressure ratios. Analytical equations for non-linear pressure distribution and velocity profiles along the channel axis are(More)
In this paper, we use a lattice Boltzmann model (LBM) for simulation of rarefied gas flows in microchannels at high and moderate Knudsen numbers. The lattice Boltzmann method uses D2Q9 lattice structure and BGK collision operator with single relaxation time. The solid wall boundary conditions used in this paper are based on the idea of bounceback of the(More)
A thermal lattice Boltzmann method (TLBM) is used for analysis of flow and heat transfer in two-dimensional channels. Simulation results are presented for thermal Couette and thermal Poiseuille channel flows. Analytical solution for temperature field in hydraulically and thermally developed flows are used to verify the current TLBM results. The method is(More)
Advance metering and reliable communication are two crucial technologies in Smart Micro-Grid (SMG), with which electric power system become more intelligent and easier to be controlled. And then the system can provide better quality electric power service for users, great efficiently utilize renewable energy, and decrease carbon emission. Based on(More)
In this paper, the lattice Boltzmann method is reviewed for specific applications to numerical simulation of multiphase flow problems. A thorough literature review regarding the multi-phase lattice Boltzmann method was conducted with special focus on flows with large density and viscosity ratios between the two phases. A multiphase model with the capability(More)
