vDotcAlphal in alphaEqn
 

Hi, Foamers!
I'm studying on interPhaseChangeFoam and trying to modify the source term in alphaEqn. By referring to some documents (https://www.researchgate.net/profile...-Phenomena.pdf), each term solved in MULES was clarified except to vDotcAlphal.

MULES::explicitSolve
(
geometricOneField(),
alpha1,
phi,
talphaPhiCorr.ref(),
vDotvmcAlphal,
(divU*alpha1 + vDotcAlphal)(),
1,
0
);

doesn't this code solve the dizcretized equation of transport equation (2,26)?

If so, integrated al * av * (rho_vdot/rho_v - rho_ldot/rho_l) seems to be equal to vDotcAlphal.

Please your advice.
