Comparison Between Surface Heating and ...

Three dimensional numerical simulations are conducted on the CANDU Moderator Test Facility (MTF). Heat generation is modelled through both surface heating employed in experimental setups and volumetric heating, the actual heating method in real reactor. The result shows that while the asymmetry in temperature distribution is visible in both cases, and the locations of hot and cold zones are similar, but the temperature range is different. Although the heat input to both cases is identical but the temperatures are better distributed in volumetric heating case since the heat source is more uniformly distributed in the liquid.
