Real-Time Visualization and Pressure Diagnostics for Neutron Generator Encapsulation

Experiments were conducted using an approximate model of the MC4380 neutron generator to obtain data on the encapsulation process for this component. Visual data (video) and transient pressure traces were collected. The purpose of the experiments was to provide preliminary validation data for modeling encapsulation mold-filling processes using the GOMA finite element fluid dynamics code. Both particle-free and particlefilled fluids were used to provide data for varying levels of computational complexity. This report gives a review and interpretation of the experimental results, and suggestions for GOMA validation activities.
