| 英文摘要 | Virtual mass force is an indispensable component in the momentum balance involved with dispersed particles in a multiphase system. In this work the accelerating motion of a single solid particle is math-ematically formulated and solved using the vorticity-stream function formulation in an orthogonal curvi-linear coordinate system. The total drag coefficient was evaluated from the numerical simulation in a range of the Reynolds number (Re) from 10 to 200 and the dimensionless acceleration (A) between -2.0 to 2.0. The simulation demonstrates that the total drag is heavily correlated with A, and large decel-eration even drops the drag force to a negative value. It is found that the value of virtual mass force coef-ficient (CV) of a spherical particle is a variable in a wide range and difficult to be correlated with A and Re. However, the total drag coefficient (CDV) is successfully correlated as a function of Re and A, and it increases as A is increased. The proposed correlation of total drag coefficient may be used for simulation of solid-liquid flow with better accuracy.
