The Inversion of Concrete Thermal Conductivity Using Least Squares Finite Element Method

Abstract:

This paper adopted the least squares of finite element method to calculate the thermal conductivity of concrete in annular region according to the internal temperature of concrete in one-dimensional steady-state heat conduction. The concrete in annular region was divided into several kinds of materials along the radius when computing thermal conductivity. The results that the ratios of the thermal conductivity of different radius are no more than one order of magnitude prove that the least squares finite element method has a high precision.
