Research Abstract |
In order to apply the Boltzmann/Navier-Stoke hybrid solver, which had already been developed, to multi-physics flow problems, a virtual flux method is incorporated in the Navier-Stokes solver so that fluid-solid interaction problems can be solved on a Cartesian grid. The reliability of the solver is examined in the numerical simulation about a reciprocating compressor. The obtained numerical results are in good agreement with experiments. For the Boltzmann solver, a novel moment base Boltzmann method is developed to save the necessary computational memory. The moment base Boltzmann method is efficient, especially for applying it to multi-physics problems, such as two-phase flow problems.
