Hi everybody

In a pipe, with FLUENT, I want to simulate liquid-solid as the Eulerian-Eulerian method, and for boundary condition, I selected velocity inlet, and slip velocity is very important for me.
now my question:
the inlet velocity for each phase should be the same?
if inlet velocity is the same, slip velocity can be calculated? or for calculation of slip velocity, inlet velocity for phases should be different?

thanks

Slip velocity is affected by velocities at the inlet, however, it is also affected by many other parameters. Therefore, different or same velocity at the inlet for two phases is not a requirement for slip to exist. At the inlet, conditions should be set as per the available data.
