κ-ε和κ-ω的区别、优缺点以及适用范围？

这个在一般的湍流模型书籍里面都有介绍，你自己找一下吧。

也许有吧

哪些湍流模型的书 ma
turbulence theory by caishutang and yulu liu
turbulence by shixionggang
turbulence(?) by douguoren
engineering turbulence by liangzaicao
turbulence by hinze
turbulent flows by pope
turbulence modelling and ? by durbin

κ-ε和κ-ω的区别
Their difference lies on the selection of scale. In essence, ε, ω are used to determine a scale. ε is related to dissipation.
优缺点以及适用范围？: different models have different applicaiton range, this is the reason there is no general model which is applicable to all turbulent flows. Engineers need to developed new model for specific cases if needed.

优缺点 comment could also found in the heat transfer book by chenjingren.

在赵大侠翻译过的FLUENT相关内容中有这些模型的区别。你也可以在HELP中直接找到，当然是英文的了！
