Numerical Simulation of Free Surface Behavior In Spallation Target With Openfoam
The spallation target in accelerator driven systems (ADS) couples the subcritical reactor core with accelerator. Design of a windowless target has to ensure the formation of a stable free surface with desirable shape, to avoid local overheating of the heavy liquid metal (HLM). To investigate the free surface behavior of the spallation target, in this paper, OpenFOAM, an opened CFD software platform, is used to simulate the formation and features of the free surface in the windowless target. The numerical studies consist of two parts. In the first part, VOF method is utilized as the interface-capturing methodology to simulate the shape and dynamic behavior of the free surface. The second part concentrates on the effect of turbulent models, such as k-ε model and Reynolds stress model, on the velocity field and the free surface shape. The effect of various parameters, such as flow velocity and outlet pressure, on the behavior of the free surface is investigated. Based on the numerical results achieved, recommendations on such parameters are made for the future design of windowless targets.
