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
