betaMaxDarcy Class Reference

Compute betaMax through the definition of the Darcy number, quantifying the viscous-to-porous forces ratio Da = nu/betaMax/L/L where nu is the bulk viscosity and L is a characteristic length. The latter is either supplied directly or computed as the. More...

Detailed Description

Compute betaMax through the definition of the Darcy number, quantifying the viscous-to-porous forces ratio Da = nu/betaMax/L/L where nu is the bulk viscosity and L is a characteristic length. The latter is either supplied directly or computed as the.

  • 2D: area of the inlet patches divided by the span in the empty direction
  • 3D: the hydraulic diameter of the inlet patches
