Pressure loss of thick and sharp edged orifice | calculate mass flow rate | overall flow regime | constant influence of friction | arbitrary cross sectional area

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Calculation of pressure loss in thick edged orifices with sharp corners at overall flow regime for incompressible and single-phase fluid flow through an arbitrary shaped cross sectional area (square, circular, etc.) considering constant influence of surface roughness.

Generally this function is numerically best used for the compressible case, where the pressure loss (dp) is known (out of pressures as state variable) in the used model and the corresponding mass flow rate (M_FLOW) has to be calculated. On the other hand the function dp_thickEdgedOverall_DP is numerically best used for the incompressible case if the mass flow rate (m_flow) is known (as state variable) and the pressure loss (DP) has to be calculated. See more information.
