| Abstract: | FLUENT software was employed to simulate the temperature-field and flow-field of AP1000 passive residual heat removal heat exchanger (PRHR HX),and investigate its heat-transferring and flow characteristics. Through comparative analysis of the distributions of temperature-field and flow-field in different locations at the same time,and the variations of temperature-field and flow-field in the same location at different time,heat-transferring process and natural convection situation of PRHR HX were understood... |
