Urgently Need the code of Lift force and VM force

Kai Yan

I urgently want to get the code section of lift force and virtual mass force in two-fluid model when simulating bubbly flow.

In bubbly flow, the formulations of lift force and virtual mass force seem to be complicated. For instance, there are 2 symbols of "cross product" in the formula of lift force, which makes me confused in code implementation.

Would you give me the code section of lift force and virtual mass in bubbly flow?

Or how can I get the code section?

Thanks!
