增维精细积分法在围护结构温度场中的应用

摘要

对增维精细积分法在建筑围护结构温度场中的应用进行研究.对空间域进行有限元离散,获得以节点温度表示的状态方程;基于增维精细积分法,导出了求解围护结构温度场的逐时递推公式.与ANSYS10.0比较,增维精细积分法是求解建筑围护结构瞬态温度场的一种高精度的数值计算方法.%The application of the increment-dimensional precise integration method in a temperature field for palisade structures was investigated. The finite discretion is carried out for a spatial domain,the state equations expressed by nodal temperatures were obtained. The step-by-step formula used in solving a temperature field for the palisade structures were deduced. Compared with ANSYS10.0.the increment-dimensional precise integration method is an higher accuracy one of solving the non-steady state temperature field for the palisade structures.
