Hello OpenFoam community,

in order to determine the fluid torque around a throttle disc's axis i want to use OpenFoam. the mass flow rate [kg] as function of the Valve opening [%] as well as fluid temperature and bosst pressure are available as inlet conditions. I want to simulate the throttling process during a given time (50 ms)

• t[ms] | Opening[%] | mass flow rate [Kg/h]
• 0 | 53 | 8640
• 20 | 49 | 6480
• 35 | 41 | 4320
• 50 | 36 | 2160
• 60 | 0 | 0

boost pressure at inlet 3,5 bar. Fluid temperature is 65°C. throttle Diameter is about 120mm.

which solver would you recommend? should i work with moving mesh/dynamic mesh? is there any useful tutorials using Openfoam in this regard?
i would be thankful for any suggestions/ starting Points or even experiences running such Kind of simulations in OpenFoam.

Many thanks in advance.
