中文摘要	The flow field in the hot gas chamber of the High Temperature Gas Cooled Reactor (HTGCR) was studied with the Computational Fluid Dynamics (CFD) program CFX5. On the basis of the experimental studies, the velocity field, pressure field and temperature field in the hot gas chamber and hot gas duct were obtained, and the simulation's accuracy and reliability were validated by comparison with the results of previous experiments. Two other design schemes of the hot gas chamber were calculated in order to determine which hot gas chamber would be optimal for minimizing temperature differences at the inlet of the heat exchanging components. The results indicated that there was much highly turbulent twisting flow in the hot gas chamber, which was responsible for the excellent temperature mixing effect of the hot gas chamber. But the flow in the rib region was calm, and this fact hindered the heat transfer between the hot and cold gas. The temperature mixing coefficient increases with the increase of the hot gas duct's distance from the hot gas chamber. The hot gas chamber without ribs was more beneficial to the heat transfer between air flows with different temperatures, so the hot gas chamber without ribs was indicated as the optimal design.
