Detailed Description

template<class CloudType>
class Foam::NonSphereDragForce< CloudType >

Drag model for non-spherical particles.

The drag coefficient is given by:

$Cd = \frac{24}{Re} (1 + a Re^{b}) + Re \frac{c}{Re + d}$

Where $a$ , $b$ , $c$ , and $d$ are coefficients, calculated as functions of $phi$ . $phi$ is the ratio of the surface area of a sphere with the same volume as the particle to the actual surface area of the particle, and must be between 0 and 1.
