In this process , the stretched function is used to make grids smooth and gradual . as the flow field solver is developed for hybrid grids , which solving n - s equations on unstructured grids , the baldwin - lomax ( b - l ) turbulent model is adopted on unstructured grids 在流場求解中,本文發(fā)展了混合網(wǎng)格的求解技術(shù),流場求解程序具有一定的通用性,并且對于把baldwin - lomax ( b - l )湍流模型用于非結(jié)構(gòu)網(wǎng)格做了研究。
