Flow measurement of a two-phase fluid around a cylinder in a channel using particle image velocimetry
The particle image velocimetry (PIV) flow measurement technique was used to study two-phase flow over cylindrical rods inserted in a channel. For the two-phase flow study, a mixture of water and small air bubbles was used. The water flow rate was 378 cm{sup 3}/s and the airflow rate was {approximately}30 cm{sup 3}/s. The water was seeded with fluorescent particle tracers in order to record the position of the particles and the air bubbles independently. Then the data were analyzed to obtain the velocity fields for both experiments. One of the major concerns with steam generator operation is the tube vibration caused by turbulent flow buffeting. The vibration can cause wear on the tube joints that may eventually lead to ruptures and leaks. This repair procedure can be very costly. To help avoid this problem, experimental data are needed to test the empirical correlations that predict the behavior of the turbulent flow around the cylinders. The PIV flow measurement technique can be used to acquire that experimental data.
