Detailed Description

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

Particle secondary breakup model, based on the references:

Pilch, M., & Erdman, C. A. (1987).
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.
International journal of multiphase flow, 13(6), 741-757.
Guildenbecher, D. R., López-Rivera, C., & Sojka, P. E. (2009).
Secondary atomization.
Experiments in Fluids, 46(3), 371-402.

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
