| 英文摘要 | Plate structures with active cooling are widely used, and rapid evaluation of the temperature performance is of interest. In this paper, an analytical model is proposed for the prediction of maximum temperature and temperature distribution of plate structures with active cooling channel. The analytical model has three types of input parameters including thermal boundary conditions, material properties, and geometry parameters. Solution procedures under different thermal boundary conditions, including heat flux and convective heat transfer, are discussed respectively. The model with heat flux boundary (MHF) is established based on the principle of energy conservation. The model with convective heat transfer boundary (MCHT) is established based on the method of second order function fitting the real heat flux distribution. The materials of the plate structures are aluminum alloy and titanium alloy. The results show that the analytical model is able to predict the maximum temperature with an error of less than 4% compared to the numerical method. The analytical model is able to quickly and accurately evaluate the thermal protection performance of the active cooling structure. |
