| Abstract: | For underground buildings,the roofs are mostly semi circular arch.This kind of boundary made the heat transter calculation complicated.In order to simplified the calculation,the heat flow rates of semi circular arch were often substituted by its simplified model the flat roof.In this paper,for same object the two model are computed and compared.The result is that the simplified model has considerably error and should be modified. |
