Information
Switch to the diagram or equation layer to see the model of a Modelica.Fluid bend using Fluid.Dissipation pressure loss calculations .
This model executes pressure loss calculations out of the Fluid.Dissipation library for a bend of an incompressible and single-phase fluid flow considering surface roughness. Both the compressible case, where the mass flow rate (M_FLOW) is calculated in dependence of a known pressure loss (dp) and the incompressible case, where the pressure loss (DP) is calculated in dependence of a known mass flow rate (m_flow) are modelled.
