Abstract :
We propose an advanced multi-components expansion method (AMCEM), which is a modification method of Lattice Boltzmann method (LBM) to obtain multi-components LBM model from single component LBM model. This modification method has advantages in point of flexible application to various LBM models and possibility of coupling different LBM models. We show an overview and verify analytical conservations of physical quantities and numerical results of AMCEM. Furthermore, we discuss parallel performance of AMCEM.
