Detailed Description

template<class CloudType>
class Foam::PilchErdman< CloudType >

Particle secondary breakup model, based on the reference:

Pilch, M. and Erdman, C.A.
"Use of breakup time data and velocity history data
 to predict the maximum size of stable fragments for acceleration
 induced breakup of a liquid drop."
Int. J. Multiphase Flows 13 (1987), 741-757

The droplet fragment velocity is described by the equation:

\[ V_d = V sqrt(epsilon)(B1 T + B2 T^2) \]

Where: V_d : fragment velocity V : magnitude of the relative velocity epsilon : density ratio (rho_carrier/rho_droplet) T : characteristic break-up time B1, B2 : model input coefficients

The authors suggest that: compressible flow : B1 = 0.75*1.0; B2 = 3*0.116 incompressible flow : B1 = 0.75*0.5; B2 = 3*0.0758
