The Simulative Analysis of the Thermal Resistance Value of Hollow Block with Different Number of Air Layers and Length with FEMLAB Software

摘要

This paper, with the help of FEMLAB Software, analyzed the change of thermal resistance value of the same hollow block with different number of air layers or with the same rate of holes but different length of air layers and came to such a conclusion that the thermal resistance value can be promptly raised by increasing the number of air layers of the hollow block but decreased when an air layer is equally divided into several holes.
