Finite element simulation of thermal performance of medium lightweight foamed concrete self-insulating block wall
Based on the finite element simulation of the thermal experiment by ABAQUS,the thermal perfor-mance of the inner blade thickness,the type of insulating core material and the thickness of insulating core ma-terial are analyzed.The results show that:ABAQUS finite element software has high accuracy.The thermal re-sistance value obtained by writing Python script and software post-processing is more efficient and accurate than the traditional theoretical method.When the total thickness of the wall is 200mm,the thermal resistance value of all specifications of the wall is less than 3.3(m2·K)/W,and the total thickness of the wall is 240mm,the thermal resistance value of the wall is less than 3.3(m2·K)/W.When the thermal resistance of EPS insulating core material is less than 3.3(m2·K)/W,and XPS,SEPS and SXPS insulating core are more than 3.3(m2·K)/W,and the total wall thickness is 260mm and 300mm,The wall thermal resistance of all thermal insulating core materials is greater than 3.3(m2·K)/W.
