EXPERIMENTAL INVESTIGATION OF THE UNSTEADY TWO-PHASE FLOW THROUGH PERFORATED PLATES
The coolant flow across the perforated dip plate during a hypothetical core disruptive accident (HCDA) in a liquid metal fast breeder reactor was simulated in a one- dimensional model. Experiments with a water - air mixture as fluid were run by varying the following parameters : geometry of the dip plate (perforation ratio, number of the holes), height of the fluid head over the dip plate, air volumetric fraction, size of the air bubbles, acceleration of the fluid. The pressure drop across the dip plate, the forces acting on the dip plate and on the upper plate, acceleration and displacement of the piston, the air volumetric fraction and the size of the air bubbles were measured in a wide range of Strouhal and acceleration numbers. The flow pattern downstream the dip plate was filmed with a high speed camera.
