| Abstract: | According to the characteristics of heat transfer,the wallbody strucute in China can be divided into three typesheavy,medium and light.Using the theory on unsteady heat transfer,a computer simulation is performed.The effect of the roots ai of equation B(s)=o on the reaction coefficients and the effect of the number of terms in the reaction coefficient expression on the heat transer calculation are analyzed.The number of the terms in the reaction coefficients for different wall types are determined,that is,n=96 for heave wall,n=72for medium wall and n=48for light wall.Therefore,the method of heat transfer reaction coefficient is improved. |
