In this study, we present the origin of spurious velocity field in the two-phase fluid flows using the continuum surface tension methods. Typically, the surface tension force is not a gradient of a potential function. Therefore, the gradient of the pressure field can not match the surface tension force in equilibrium state. This leads to spurious velocity field. We numerically demonstrate the origin of spurious velocity field.
