| Abstract: | With finite difference method,three dimensional temperature field and thermal resistance of new type energy saving building blocks were calculated . Results of calculation reflects the steady thermal characteristics of building blocks more accurately. Using theory about unsteady heat transfer and simulated calculation by computer, hollow building blocks were analyzed. A definite value of numbers of reaction coefficient was proposed in this paper by comparing the method of equivalent density with the method of equivalent length. Method of heat transfer reaction coefficient is perfected and a better condition is produced for use of this method. |
