FunctorErgunDragCoefficients
Material providing linear and quadratic drag coefficients based on the correlation developed by Ergun.
This class implements the Darcy and Forchheimer coefficients for the Ergun drag force model which is discussed in detail in Computation of friction factors and pre-factors. We also give details on the definition of Darcy and Forchheimer coefficients there.
To summarize, this class implements the Darcy coefficient as
where is the hydraulic diameter defined as where is the diameter of the pebbles in the bed. The Forchheimer coefficient is given as
where we have made the multiplication explicit, instead of writing , to make the 1.75 factor from the Ergun wikipedia page more recognizable.
