This paper presents a numerical study on the thermal distribution and cooling performance of indirect-drive inertial confinement fusion (ICF) cryogenic target which requires a highly uniform temperature distribution around its capsule. Computational Fluid Dynamics, CFD models are developed for both stable and transient fluctuating cooling conditions. Experimental validation is undertaken and the predicted amplitudes by CFD simulation prove to be in good agreement with those measured in the experiments. The investigation results indicate that the He-H2gas filled in thehohlraumhas quite an impact on the thermal environment around capsule, and improvements in the uniformity of capsule surface temperature can be made by either reduction of filling gas pressure or increase of He content in gas mixture. Fluctuation of cooling temperature deteriorates the uniformity of capsule surface temperature when compared with stable cooling conditions. However, the fluctuation amplitude can be attenuated to less than 10% in the presence of filling gas, and increasing the content of H2in filling gas gives rise to further attenuation.
