The location of the transition region of slug flow on flow pattern maps, play important role in the dynamic response of the structure to the flow. (FIV) has been given increasing attention in various engineering fields including petroleum pipelines, power. Slug flow and stratified flow patterns induced significant vibrations in the examined structure. In recent years, two-phase flow induced vibration. The results show that the magnitude and nature of vibrations of the piping structure is largely affected by the frequency and size of the bubbles upstream, vortex creation by pressure fluctuation downstream, liquid flow rate, and the flow pattern upstream.

Also, a capacitance sensor was used to measure the two-phase void fraction. Proximity sensors have been used to capture the pipe response in two orthogonal directions. The liquid velocity fields have been obtained using Particle Image Velocimetry (PIV) along with post processing algorithm for phase discrimination. Several flow regimes from bubbly to stratified-wavy flow have been analyzed to evaluate the effects of flow pattern, phase redistribution, bubble frequency, and liquid flow rate on the vibration of the structure. Investigation of two phase flow downstream the orifice and its effects on vibration of the piping structure have been carried out. The current work studies air-water flow through a ½-inch flow restricting orifice installed in a 1-inch pipe.
