... reflector.. In this work, a comparison between four different geometries of the secondary reflector of an LFR by means of Computational Fluid Dynamics (Ansys Fluent®) is carried out. It is taking into account the variation of the tilt angle of 45°, 50°. 60° and 70° in the trapezoidal geometry...

... melters. A high-fidelity, computational fluid dynamics (CFD) model of the pilot-scale DM1200 melter has been developed to provide an understanding of the heat transfer and fluid dynamics within the WTP melters. Monitoring of the non-radioactive pilot-scale system has been primarily done through visual...
