functiondp_thickEdgedOverall_DP

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

Extends from Modelica.Icons.Function (Icon for functions).

Information

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