Given the multiphase flow of phases: and mass flowrates
\dot m = \sum_\alpha \dot m_\alpha |
A = \sum_\alpha A_\alpha |
s_\alpha = A_\alpha/A |
\sum_\alpha s_\alpha = 1 |
u_m = \sum_\alpha s_\alpha \cdot \dot u_\alpha |
q_\alpha = \dot m_\alpha / \rho_\alpha = A_\alpha \, u_\alpha \Rightarrow \dot m_\alpha = \rho_\alpha \, A_\alpha \, u_\alpha |
For homogeneous pipe flow: and volumetric shares are going to be:
s_\alpha = \frac{\dot m_\alpha}{\rho_\alpha} \cdot \left( \sum_\beta \frac{\dot m_\beta}{\rho_\beta} \right)^{-1} |
