A hot gas mixing experiment of HTR-PM reactor core outlet is proposed to measure and analyze the actual heat mixing performance and flow resistance property of this mixing structure. The design criteria and parameters of the hot gas mixing experiment are determined according to similarity criterion. In addition, the numerical simulation of the temperature and pressure profile of the designed experiment installation is carried out by using FLUENT software. The mixing performance and the resistance property of these two structures are analyzed and compared. The characters of mixing performance and the coefficient of flow resistance are obtained with the change of Reynolds number of flow in hot gas duct. How the flow and heat mixing of the mixing structure entrance the self simulation mode is discussed. According to numerical simulation and theoretical analysis, the heat mixing performance and the flow resistance property can be obtained by the scale model experiment and the following numerical simulation. The flow resistance property should be described in a more detailed and reasonable way which requires the accomplishment of the experiment.
