摘　　要：采用基于有限容积法的Fluent软件,对190mm×240mm×115mm烧结页岩空心砖进行了当量导热系数的三维数值模拟和计算。模拟中主要考虑孔型、孔的长宽比、孔的排列数、孔洞率4个因素。模拟结果表明:矩形孔的当量导热系数最小,并随着矩形孔长宽比的增加,当量导热系数逐渐减小;另外,随着孔排列数、孔洞率的增加,空心砖的当量导热系数逐渐减小。The equivalent thermal conductivity of fired hollow shale brick with the size of 190 mm × 240 mm × 115 mm is simulated numerically and calculated by FLUENT software based on the finite volume method. The results show that four factors of hole＇s shape,aspect ratio,arrangement and perforation volume have significant effects on the equivalent thermal conductivity. The equivalent thermal conductivity of rectangular hole is minimum,higher rectangular hole aspect ratio,the smaller thermal conductivity of hollow bricks. In addition,hole arrangement,porosity are higher,the smaller its thermal conductivity.
