i have modeled a 10'' and 14'' single plate check valve(please see Image and 3d PDF ) and want to perform Flow Simulation the following data ate available with me,
1)Inlet Volume flow rate 850m3/hr for 10'' valve and 1530 m3/hr for 14'' valve.
2)Inlet Pressure 10bar.
Now i want to find,
1) the pressure drop across the inlet and outlet and it should not exceed above 0.5 bar.
2) Velocity of fluid.
3)Force and torque acting on disk at different closing angle (from 0-55 degree) also for different mass flow rate
coming negative in outlet side when check with surface parameters( I've set inlet at .236 m3/s(850 m3/hr) outlet condition at 9.5 bar pressure) also the Pressure drop is different for different flow rate.(due to continuity equation,may be).
Can any one guide me how to actually find the pressure drop and why the negative mass flow rate is coming at outlet.
Any help on this problem would be greatly appreciated! Thank you in advance!
