[2M17] Evaluation of Gas Entrainment Flow rate by Numerical Simulation
Keywords:Sodium-cooled fast reactor, Free surface vortex, Gas entrainment, Numerical simulation
On the gas liquid interface in a sodium-cooled fast reactor, gas entrainment can be caused by free surface vortices, which may result in, e.g. disturbance in core power. Therefore, it is important to predict accurately the entrained gas flow rate in the process of fast reactor design. In this study, the entrained gas flow rate in a simple experiment is evaluated by a high-precision numerical simulation under various downstream pressure condtions. The simulation results of entrained gas flow rate increases with decrease in the downstream pressure and the flow patten in a suction pipe also changes with the change in the downstream pressure. Such results agrees well with the experimental measurements.
