Validation

CFD MAN

If you have few minutes, pls respond: 1) Is there any bench mark tests case for validation of particle flow? What about individial force validation: pressure force, virtual mass force, saffman lift force etc.

2) When I am validating the turbulence parameters against the experimental data (from root mean square of the velocity components from the experiment I am calculating the k for example) for a bubble flow using VOF, it does not match. Do you have any suggestions?

Do you think I have to modify the k-e equation?

3) Whats the best way to validate the VOF free surface modeling?
