Calculation of pressure loss for a valve with different geometries at overall flow regime for incompressible and single-phase fluid flow in dependence of its opening.
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_severalGeometryOverall_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.
