摘要
飞机复杂外形的绕流数值模拟在飞机型号研制中有重要的作用 ,也是数值模拟中比较复杂的问题之一。本文采用基于Octree技术的方法生成非结构四面体网格 ,用耦合隐式离散的方法进行有限体积离散 ,利用此方法对某型飞机的绕流特性进行了数值模拟 ,收到较好效果。
Numerical Modeling of Flows over a Complicated-Shape aircraft,a relatively Complicated numerical simulation,plays increasingly important roles. In the paper , unstructured tetrahedral meshes have been generated using the method based on Octree technology and a coupled implicit approach has been used to disperse the equations according to finite volume. The flow characteristics of a aircraft is modeled with the method and satisfactory results are obtained.
