Ask The GSS Expert : How does the Pressure Potential and the coordinate system effect the pressure in FloEFD?

posted Nov 27, 2017, 11:22 PM by Songyi Han
For several application areas, it is crucial to consider the hydrostatic height, for example for the design of pumps or fans. For models of high geodetic head and/or for fluids with high density, the gravitational head is significant. It is important to understand how FloEFD works to avoid any mistakes.

Setting up a FloEFD project user may ask himself the following questions :
  • Do I need to correct the environment pressure (to take into account the piezo pressure) for FloEFD models of a high geodetic head, if there are openings at different heights?
  • Does FloEFD take into account gravitational head correctly?
  • How do you define the pressure at these openings?
  • My pressures are too low or too high in the equipment. Is it normal?
