这项工作的主要目的是提供精确的数值解选定的流场和比较和评估的性能选定的湍流模型与实验结果。四个流行的湍流模型已被测试和验证的实验数据往往湍流。这些模型是：（1）Wilcox的两方程k-ω模型，（2）Launder和Sharma的两方程k-ω模型，（3）Menter的两方程k-ω/k-ω SST模型，（4）Spalart和Allmaras的一方程模型。研究的流动是由混合层、圆形射流、平面射流、平面尾流和可压缩混合层组成的五种自由剪切流;以及由不可压缩平板、马赫数为5的绝热平板、分离边界层、轴对称激波/边界层干扰和RAE 2822跨音速翼型组成的五种边界层流。这些流动的实验数据已经很好地建立，并已广泛用于模型开发。结果显示在以下四个部分中：部分A描述了运动方程和边界条件;部分B描述了模型方程、常数、参数、边界条件和数值实现;部分C和D分别描述了自由剪切流和边界层流中模型的实验数据和性能。
The primary objective of this work is to provide accurate numerical solutions for selected flow fields and to compare and evaluate the performance of selected turbulence models with experimental results. Four popular turbulence models have been tested and validated against experimental data often turbulent flows. The models are: (1) the two-equation k-epsilon model of Wilcox, (2) the two-equation k-epsilon model of Launder and Sharma, (3) the two-equation k-omega/k-epsilon SST model of Menter, and (4) the one-equation model of Spalart and Allmaras. The flows investigated are five free shear flows consisting of a mixing layer, a round jet, a plane jet, a plane wake, and a compressible mixing layer; and five boundary layer flows consisting of an incompressible flat plate, a Mach 5 adiabatic flat plate, a separated boundary layer, an axisymmetric shock-wave/boundary layer interaction, and an RAE 2822 transonic airfoil. The experimental data for these flows are well established and have been extensively used in model developments. The results are shown in the following four sections: Part A describes the equations of motion and boundary conditions; Part B describes the model equations, constants, parameters, boundary conditions, and numerical implementation; and Parts C and D describe the experimental data and the performance of the models in the free-shear flows and the boundary layer flows, respectively.
