Detailed Description

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

Particle secondary breakup model based on Pilch-Erdman total droplet breakup model.

Reference:

    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.
    DOI:10.1016/0301-9322(87)90063-2

The droplet fragment velocity is described by the equation:

\[ V_d = V \sqrt(\epsilon)(B_1 T + B_2 T^2) \]

where

\( V_d \)	=	Fragment velocity
\( V \)	=	Magnitude of the relative velocity
\( \epsilon \)	=	Density ratio (rho_carrier/rho_droplet)
\( T \)	=	characteristic break-up time
\( B_1 \)	=	Model coefficient
\( B_2 \)	=	Model coefficient

Where:

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
