摘　　要：流体颗粒的靠近接触过程是流体颗粒聚并过程中的一个非常重要的的阶段.Svendsen & Luo的靠近过程模型能应用于等径和非等径流体颗粒的靠近过程,但存在液膜半径偏大的问题,对Svendsen & Luo模型进行了改进,改进的靠近过程模型计算的最大液膜面积较Svendsen & Luo靠近过程模型计算的液膜面积减小约30%.Approach processes for fluid particles is an very important stage of coalescence processes of fluid particles. Svendsen ＆ Luo＇ s model gives the first reasonable approximation for the approach process between two unequal sized particles. But the liquid film area calculated by Svendsen ＆ Luo＇s model is a little bigger. An improved approach process model has been proposed. The film area calculated by the improved model is 30 percent smaller than that of Svendsen ＆ Luo＇ s model.
