关于湍流仿真的经典文献，对气象雷达和流体力学专业等相关专业的人士非常有参考价值。(The standard k-E. equations and other turbulence corrections are evaluated and reported with respect to their applicability in three-dimensional flows. The turbulence models are formulated on the assumption that an ilsotropic eddy viscosity and the modified Boussinesq hypothesis adequately describe the stress distributions, and that the source of predictive error is a consequence of the modeled terms in the ke equations. Turbulence model corrections are incorporated to investigate their impact on these errors. Predictions from various turb+lence models are compared with experimental data froq an isothermal 3-D configuration. The data combsons delineate the relative advantages and disadvantages of various modifications. The k-E model perfbrms competitively with other model corrections and in some instances is judged to be superior than the modzfied treatments. However, given the additional computational time and the marginal superiorityofthe investigated models, it is )
