Source term in two-phase flow
 

Hello, Could you like please indicate me what is the error in these source terms included in two-phase flow axial momentum equations :

source = (2.0*time-1.0)*C_VOF(c,t) ;/* C_VOF(c,t) of primary phase */ (in primary phase momentum equation)

source = (2.0*time-1.0)*C_VOF(c,t) ;/* C_VOF(c,t) of secondary phase */ (in secondary phase momentum equation)

Best regards, Chouki
