由于太阳能在时间上的非连续性使得太阳能腔式吸热器要频繁地经历不同的启动过程，对腔式吸热器在冷态启动、温态启动和热态启动过程中的热性能进行了模拟。计算得到了吸热器在三种启动过程中入口处所需的太阳光能量，可为定日镜场的布置及控制提供理论指导，同时还得到了吸热器在启动过程中热效率及辐射热损失、对流热损失随时间变化的曲线。
A solar cavity receiver frequently experiences different start-up processes because of the noncontimfity of solar energy in time. The thermal performance during three start-up processes, including cold start-up, warm start-up and hot start-up, was numerically simulated. The solar energy that the aperture of cavity receiver required was calculated during three start-up processes, and it can provide theoretical guidance for the layout and control of heliostat field. The curves of thermal efficiency, radiative thermal loss and convective thermal loss were also gained.
