    Abstract :

    In the case of two-phase flow, the momentum fluxes due to flow turning elements like bends, elbows etc.at the end of pipe are the major cause of flow-induced vibrations (FIV) .In this work, an experimental set up has been developed to study the effect of two phase flow (air-water) characteristics on momentum flux for the different support condition of test section i.e. cantilever end condition and both end fixed condition. To carry out the experiments, the test section is made of steel material of 0.0239 m in diameter and 1.2 m in length. The experiments are carried out for different flow regimes and void fraction. The mass flow rate of air and water flowing through test section are varied simultaneously to obtain the different types of flow characteristics or flow regimes. At the same time, the momentum flux induced due to two phase flow (air-water) are measured using momentum flux apparatus(load cell) fixed close to at the exit of test section. The results of experimental analysis are compared with those obtained with CFD (Fluent 15.0) analysis software. And it is seen that there is good agreement between the results of experimental and CFD analysis and found to be satisfactory with 4 to 20 % error for different support end condition i.e. cantilever end and both end fixed for all types of flow characteristics.
