Momentum source calculation
I am trying to calculate the momentum source as shown -
source = mdot *(increase in velocity) /cell volume.
where, mdot = mass flow rate through each cell face.
cell volume = volume of each cell in the fluid zone, where source has to be applied.
The flow is steady and fluid is moving in a pipe in x direction.
When i give the calculated source value as x momentum source term in fluent, I am not getting the expected velocity increase.
Can anyone tell me is this the correct way of calculating momentum source :confused:
Thanks in advance,
