.Modelica.Fluid.Pipes.BaseClasses.WallFriction.QuadraticTurbulent .Modelica.Fluid.Pipes.BaseClasses.WallFriction.QuadraticTurbulentThis component defines only the quadratic turbulent regime of wall friction: dp = k*m_flow*|m_flow|, where "k" depends on density and the roughness of the pipe and is no longer a function of the Reynolds number. This relationship is only valid for large Reynolds numbers.
In UsersGuide the complete friction regime is illustrated. This component describes only the asymptotic behaviour for large Reynolds numbers, i.e., the values at the right ordinate where λ is constant.
