| Abstract: | The transfer phenomena in the velocity developing period of single droplet air-flowing system has been numerically simulated by computation of fluid dynamics, and the deformation and local transfer characteristics of the drop moving through the countercurrent air-flowing studied. The relationship between drag coefficients and Reynolds numbers has been acquired at 30
