Based on the detailed and abroad investigation of the inland and overseas literatures three dimensional turbulence computation in recent 10 years , the vertical delaminating coefficient ko was introduced in normal - coordinate transform in this paper . this means = was used to displace the normal , which has been regularly used in the computation of 3d flow in recent years . the use of new coordinate is aimed to match the landform better and improve the instance that the normal coordinate mathematic models are emanative with complicated landform sometimes
在对近年来国内外三维紊流计算的有关文献进行了细致的分析研究基础上，本文将三维紊流计算中常用的坐标变换加以改进，引入垂向分层系数k _ 0 ，采用= k _ 0 ( z - ) d的变换方法，以期更好地与实际地形相匹配，改善常见坐标变换数学模型在地形复杂地区容易发散的问题，并给出了k _ 0的确定方法。
