Inversion Simulation for Heat Conductivity of Building Envelope
摘要
Abstract
This paper presents a numerical model to resolve the unidirectional non-linear inverse problem of heat conduction in transient state of buildings envelope. The temperature field is calculated with the control-volume-based numerical method and the heat conductivity is determined with the genetic algorithm. The result shows that the simulation method has high calculation accuracy and it can be applied to the identification of heat conductivity in different conditions.关键词
