| Summary: | 碩士 === 國立中正大學 === 機械系 === 89 === The article researches the heat transfer with coupling solid and fluid --- conjugate heat transfer , and uses the Lattice Boltzmann Method ( LBM ) to simulate the problem .
Recently LBM has been used to be Computational Fluid Dynamics ( CFD ) . Discretizing the Boltzmann equation for spatial and time , we can get Lattice Boltzmann Equation ( LBE ) . The collision operator LBE always uses the Bhatnagar-Gross-Krook ( BGK ) model through the Chapman-Enskog expansion , and then we can derive the equilibrium distribution function covering the Navier-Stokes equation . The operation of LBM includes two steps --- collision and propagation . According to above operation , we can get physic quality from distribution function .
First , the research simulates the simple fluid flow and heat transfer problem , and then simulates two paper from the journal to compare the result with LBM .
