【 摘 要 】

Heat transfer and pressure drop characteristics were numerically investigated in a corrugated plate heat exchanger, considering the operating conditions for the nuclear power system. The plate deformation which is induced by the large pressure difference between the hot fluid side and cold fluid side was examined using the two-way fluid-structure interaction (FSI), and then the friction factors and Colburn factors were investigated for the deformed geometry. The Colburn factors for the deformed geometry were similar to those of the previous correlations, while the friction factors for the deformed geometry were about 7% higher than those of the previous correlations in large pressure difference regime.
