Abstract

Abstract:

Background: One of the functions of the integrated head package is to cool down control rod drive mechanism (CRDM), which is realized through convective flow and heat transfer of cooling gas. Purpose: Concerning the integrated head package of ACP100 nuclear reactor, we rigorously compared the thermal-fluid computation results. The emphasis of numerical simulation and comparison was laid on the effect of gas compressibility on heat transfer of cooling gas. Methods: The complete mesh model is built by HyperMesh and the thermal-fluid computation results are simulated with commercial ANSYS/CFX software and treating fluid media as both compressible and incompressible gases. Results: The simulation results show that the gas compressibility has great impact on the distribution of temperature, velocity and pressure fields. Conclusion: Ignoring the compressibility of gas would give an underestimation of maximum temperature on CRDM surfaces, lower maximum velocity and smaller pressure drop on CRDM gaps.
