Inter-Phase Slip Algorithm (IPSA)
 

hi,all

I use the homogeneous model to simulate the free surface between oil phase and water phase. I want to know the software how to solve the problem. We all know the the multi-fluid model is solved using the Inter-Phase Slip Algorithm (IPSA) of Spalding. I hope to find this reference paper, however, it is very difficult to search this paper according to the CFX's manual book. So, I ask your help to find the paper, thank you!
