ABSTRACT: The tube inside and outside heat transfer
mechanism of Passive Residual Heat Removal Heat Exchanger (PRHR HX) was analyzed.
The calculation method of this special heat exchanger under natural convection condition
in In-containment Refueling Water Storage Tank (IRWST) was carried out. The
single-tube coupling model three-dimensional natural circulation in the IRWST
was simulated numerically using Fluent. The heat transfer and flow
characteristics of the fluid in IRWST were obtained. The comparison of the
results between theoretical arithmetic and numerical simulation showed that the
theoretical calculation method is suitable for the heat transfer calculation of
PRHR HX.
