一、RNG k−ε Model RNG k−ε Model由Yakhot和Orzag在1986年提出,称为重整化群 k−ε 模型(Renormalization Group k−ε Model)。 RNG k-epsilon Model中,通过在大尺度运动和修正后的黏度项体现小尺度的影响,而使这些小尺度运动有系统地从控制方程中去除。 RNG k−ε Model的 K 方程和 ε 方程...

The reason for C1e control missing is just because the realizable k-epsilon model doesn't actually have a C1e. Basically, the epsilon equation in the realizable model is different from the usual one and the production term, the one multiplied by C1e in the standard k-e model, is one of...
水闸是渠道或河道工程中十分重要的水工建筑物,因此水闸流的模拟也具有重要的现实意义.为提高水闸流的模拟精确度,引入较为先进的Realizable k-epsilon模型,并采用该模型对河道水闸下游水流进行了数值模拟.将模拟结果与试验数据和标准k-epsilon模型结果进行比较.结果表明,标准和Realizable k-epsilon模型均可较为准确地预测...

Unfortunately, this still does not quite suffice for the algorithmic part of our result, since the SDP can only be computed up to a finite precision in polynomial time (the running time is proportional to \log 1/\varepsilon , where \varepsilon is the desired precision). Universal rigidity ...
Utilizing a local-access model, we propose a novel primal-dual algorithm that, after O ~ ( poly ( d ) 3 ) ilde{O}(ext{poly}(d) \epsilon^{-3}) queries, outputs with high probability a policy that strictly satisfies the constraints while nearly optimizing the value with respect to a...
