Multiscale simulation coupled DRBEM with FVM for the two-phase flow with phase change process of micrometer scale particles

A multiscale computational method couple dual reciprocity boundary element method (DRBEM) with finite volume method (FVM) is developed, and used to numerically simulate the hydrothermal gasification and evaporation of micrometer scale particles in two-phase flow. The engineering applied background of the problems include: hydrogen production from biomass in supercritical. water, water mist fire suppression, etc. Numerical results shows the multiscale computational method coupled DRBEM with FDM is credible and effective. This paper also presents some valuable numerical results for these engineering problems.
