摘　　要：在Modelica语言和Dymola软件平台的基础上,建立塔式太阳能热发电系统中碳化硅泡沫陶瓷空气吸热器的一维非稳态仿真模型。仿真模型中采用体积对流换热系数和Rosseland辐射传递方程描述对流换热和辐射传热过程,空气热物性参数随温度和压力变化。该模型的仿真结果正确性得到空气吸热器实验平台的实测验证,可用于以碳化硅泡沫陶瓷为吸热体的空气吸热器动态特性预测。The one-dimensional dynamic simulation model of the silicon carbide ceramic foam air receiver is established based on Modelica language and Dynamic software. The volumetric heat transfer coefficient between air flow and the solid of the ceramic foam and the Rosseland radiation model are used to describe the convective and radiativeheat transfer in the absorber. The physical properties of the air are considered variable with the temperature and pressure. The comparisons between the experimental data and simulation results have been validated by the experimental data, which prove this model can be used in the dynamicbehaviorprediction of the silicon carbide ceramic foam air receiver.
