摘　　要：本文以八达岭塔式太阳能热发电实验电站腔式吸热器为研究对象,根据吸热器的结构和工作原理,利用热力学定律建立了吸热器系统水动力仿真数学模型,模拟了吸热器蒸发受热面系统内工质的流动,通过吸热器水动力的仿真实验从而得到在不同的太阳辐照强度下吸热器蒸发受热面入口流量的分配规律。论文结论对实际太阳能热发电站吸热器的设计及安全运行具有指导意义。This paper took overheating cavity receiver of Badaling 1 MW solar power tower plant as study object, developed a hydrodynamic simulation model for receiver based on the working principle of the superheating cavity receiver, simulated the hydrodynamic characteristics of cavity receiver, and obtained the change law of working medium mass flow in different heating surfaces with solar radiation. The results can provide some guidance to design the receiver system and to formulate the control and operating strategy for solar power tower plant.
