Dear authors, thank you very much for your excellent tutorial. I have learned a lot. Recently I'm studying multiphase flow. There was some confusion when reading the tutorial.
I consulted the literature [RLY 14] and found that the mixture velocity given in the tutorial is inconsistent with the original article [RLY 14]. May be my misunderstanding? I'm not sure about it.
The mixture velocity given in this tutorial: \mathbf{v}_m = \frac{1}{\rho_m \sum_k {\alpha_k \rho_k \mathbf{v}_m}}
while that in [RLY* 14] is: \mathbf{v}_m = \frac{1}{\rho_m} \sum_k {\alpha_k \rho_k \mathbf{v}_k}
