  Hi everybody,
  I am doing a simulation in ansys CFX of aexternal gear pump. I have problems that I want to evaluate the outlet pressure by changing the angular speed in RPM but there is an erroneous variation of the outlet pressure, since when increasing the angular speed the pressure must increase and the results show the opposite.
  I have changed the time steps but I have the same result.
  Do you know what the problem would be?
  thanks

  Hello,
  Check the pressure again for the 2870 RPM case. Do you get the 14 psi as area averaged pressure value at the outlet?
  Regards SD
