Development of Visualization Software for Thermal-Hydraulic Analysis in a Tight-Lattice Bundle using AVS

Thermal-hydraulic safety in a tight-lattice bundle has been analyzed to contribute thermal design of an advanced water-cooled reactor core. Since the analytical geometry is complicated, it is difficult to understand the analysis results using general visualization software. In this study, the visualization program for the thermal-hydraulic analysis in the tight-lattice bundle was developed using the software AVS/Express. It can reproduce the three-dimentional view and graphs of the analysis results and it is helpful in understanding the thermal-hydraulic phenomena in the tight-lattice bundle.
