      在气液欧拉多相流的大涡模拟中,有没有什么模型是把liquid或者particle相的SGS viscosity和主相的SGS viscosity联系起来的?
      就像RANS中的一种模型:
      $\begin{equation}
      \frac{\nu_{t,particle}}{\nu_{t,gas}}=(\frac{k_{particle}}{k_{gas}})^2=\frac{1}{1+\frac{t_p}{t_{fl}}}
      \end{equation}$
      其中$\nu_t$是湍流粘度,k是湍动能,$t_p$是particle relaxation time,$t_{fl}$是Lagarangian fluid time scale。
      现在像找一个类似的模型用在LES上,但是翻了好久也没翻到 :135:
