Include Viscous Work term (in fluid model)
 
Hello. I am running transient simulation for turbine stator-rotor using ANSYS CFX. There is a disc cavity along the rotating wall of rotor which shows axi-symmetric fluid structures in transient simulations when the pressure signal in the cavity start to oscilate.

In my current analysis, I forgot to put the "Include Viscous Work Term" in the fluid model and I can see that the pressure signal is not oscillating. I want to know what possible impact that might make on my simulation if I include or not include the viscous work term. An elaborative response will be highly appreciated.

Thanks

MJ
