本文采用能有效处理空心砖内部导热、对流与辐射换热耦合计算的自编程序,数值研究在外墙保温条件下空心砖墙体的当量导热系数。观察加保温层后具有不同孔洞数与排列方式的空心砖其当量导热系数的变化,以及保温层对空心砖的当量导热系数的影响。模拟结果对外墙保温层下空心砖的结构选型提供了参考依据。
In the paper, coupling calculation of conduction, convection and surface radiation in hollow brick walls can be effectively deal with by original computation code. The equivalent thermal conductivity of hollow brick walls have been predicted numerically under exterior insulation condition. The change of equivalent thermal conductivity of hollow brick of different hole number and arrangement under exterior insulation has been observed to emphasis tile influence. The simulation results provide valuable data for the hollow brick design under exterior insulation.
