This project calculates the pressure drop across an orifice restriction in a turbulent pipe flow. The simulation domain is axisymmetric with center axis along the flow direction. The orifice radius can be defined, and the geometry varied between 0 (straight orifice) and 45 degrees (opening orifice) at the orifice exit. A range of fluid and turbulence properties can be tested, as well as flow velocities.
(Note: The solver uses relative pressures.)
