水下滑翔机速度较低，其外部绕流流场由层流和湍流混合组成，其中层流段约占70％，传统单一的层流或湍流分析模型难以准确分析其水动力特性；在此提出了采用多区域的混合模型，对水下滑翔机的水动力特性进行CFD计算，获得其主要流体动力参数，通过与试验数据对比，结果表明：采用多区域混合模型计算所得的结果与实验得出结果较一致。

The speed of the underwater glider is low. Its external flow field includes the laminar flow and the turbulent flow,and the laminar flow counts 70%. The single tradition laminar flow or turbulent flow couldn’t accurate analysis the hydrodynamic characteristics. Therefore,this article puts forward a multi-region mixture model and calculates the hydrodynamic characteristics of the underwater glider by CFD so as to get main hydrodynamic parameters. Comparing them with the experiment data,it turns out that the cal-culation with multi-region mixture model is very close to that of the experiment date.
