Transient Analysis of a Molten Salt Cavity Receiver

A transient analysis of a molten salt cavity receiver is presented. A two-node model, which is the theoretical basis for transient analysis, is developed for the receiver. During the transient process, the energy variation of different part of the model is researched experimentally. Especially, a transient variation process of both the receiver surface temperature and fluid temperature is analyzed detailedly in the paper. The transient process due to the sudden change of input power is divided into three stages. The transient characteristic of the receiver is analyzed based on the three stages. Also the time constant which reflects the influence of the thermal inertia of the receiver is got from the experiment.
