摘要：

The ventilation heat transfer of CPR1000 Control Rod Drive Mechanism (CRDM) is simulated when CRDM continuous insertion action by using the ANSYS CFX software. The CRDM coils temperature, the relationship between cooling air flow and the CRDM coils temperature, CRDM air flow pressure drop in cooling channel, CRDM heat dissipating capacity and heat transfer coefficient are analyzed. The comparison between the simulated results and the test results shows that the numerical simulation method is acceptable.
