CubicInterpolation_ReCubic Hermite spline interpolation of the Reynolds number in transition regime of the Moody diagram (inverse formulation) |
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Re = CubicInterpolation_Re(0, Re1, Re2, Delta, lambda2);
Function CubicInterpolation_Re(..) approximates the Reynolds number
Re
in the transition regime between laminar and turbulent flow
of the Moody diagram by an inverse formulation of a cubic Hermite spline interpolation. See
Modelica.Fluid.UsersGuide.ComponentDefinition.WallFriction (especially Region 2)
for a detailed explanation.
