I:4 Flow in nuclear reactors

In the upper part of a BWR (Boiling Water Reactor), the gas-droplet core flow interacts with the water film on the fuel rods by droplet deposition and entrainment (annular flow regime). The net deposition on the rods needs to be sufficiently high to avoid local overheating of the fuel rods. Presently, the knowledge about droplet deposition and entrainment is limited (simple tube geometry, empirical correlations, etc.). The goal of this project is to improve the understanding of droplet deposition. The results are of use for increasing the overall performance of BWR while maintaining high safety requirements.
