Simulation of two-phase flow through porous media in OpenFOAM?

Let's consider a rectangular channel having a porous obstruction in between. I want to set up a case to simulate the changes in flow behaviour due to this obstruction using VOF (interFoam). What...

How much the interfacial tension of kerosene-air is varied on adding the span 80 surfactant to it?

I want to change the interfacial tension of kerosene-air by adding the surfactant span 80 to it. I chose span 80 because it is completely soluble in kerosene (correct me if I am wrong). Can you...

I want to simulate flow through packed bed in ansys fluent where the porosity is the function of axial direction?

It would be of immense help if anyone can suggest to me the different ways to incorporate the porosity expression in the fluent e.g. via UDF or others. I have tried to incorporate it via UDF but I...

What are some good literature on effects of hydraulic jump on multi phase intermittent slug-flow through pipe?

It is fine that slug front within pipe is assumed to be hydraulic jump. But i am looking for some work in which its analysis in terms of forces and energy loss at slug front is provided.
