Abstrakt:	The formulation of the momentum equation with the artificial viscosity term added is: HT $\frac{}{}+-(\mathit{U}\mathit{U})=-p+-\left((2+2{}_I){\mathit{S}}_i\right)+{\mathit{f}}_{\mathit{}}$ ht Graph (16) In the last equation, I i represents the numerical delta function which is equal to 1 in the cells containing the interface and 0 elsewhere in the domain. (9) and (11), a blended normal vector, HT ${\mathit{n}}_{\text{blended}}$ ht , is obtained by: HT ${\mathit{n}}_{\text{blended}}=\frac{(}{1}$ ht Graph (12)where I i ranges from 0 to 1.
