A new MCHE was experimentally investigated the thermal-hydraulic performance using the Supercritical CO2 WHR test loop sited at Kato Lab. in Tokyo Institute of Technology. The empirical correlations were derived in order to predict the heat transfer and pressure drop characteristics of the new MCHE for hot water suppliers. Beside, the thermal-hydraulic performance of the new microchannel heat exchanger was experimentally compared to the conventional tube heat exchanger types.
Molten metal freezing behavior during interaction with structure was experimentally investigated with respect to core disruptive accidents of a liquid metal reactor. The experimental results were also simulated with a reactor safety analysis code, SIMMER-III. Simulation results showed encouraging agreement with the experimental results for the penetration length both observed on stainless steel and brass structures.
