| Research Abstract |
This study performed the direct numerical simulations of solid-fluid two phase flow, and developed the stochastic model of the dispersed turbulence and the related heat transfer. The direct numerical simulation was made by the Fourier spectral method to the volume-weighted solid and fluid mean velocity. The two-phase heat transfer modeling was developed based on the random walk model to the diffusion and the two-body collision model to the mixing.
