Abstract: In this paper, a concept of virtual mass force in viscous flows is introduced through rigorous analysis of a particle transient motion at very low particle Reynolds number. For the particle transient motion at high Reynolds number in viscous flows, the corresponding virtual mass force is researched by method of vorticity analysis. The result is shown that the virtual mass force acting on a particle accelerating at high Reynolds in viscous flows has the same formulation as that in nonviscous flows.
