The most important difference between two-phase flow and single-phase flow is the random buffeting force in the two-phase intermittent flow regime. When not in the intermittent flow regime (e.g. in bubbly flow or mist flow), the vibration estimation is similar to that for single-phase flow except for the fluid density.
