Calculation of Surface Temperature for Limited Thick Plate with Constant Power Heating Based on Green's Function Method
摘要
Abstract
For computation of thermal conductivity for sheet -like material in constant power plane heating test , based on Green's Function Method , the analytical expression functions of surface temperature for limited thick plate with one side constant power heating were derived .A numerical calculation method was employed to calculate the functions , and the approximate calculation value of the functions of surface temperature showed convergence characteristic in an example of aerated concrete .Additionally , the errors of nu-merical calculation of the function brought by different plus terms and heating time were analyzed .As the number of plus terms was greater than or equal to 40, the calculation error might be less than 1%in a short time heating.关键词
