An Application of Improved Genetic Algorithm in the Study of Inverse Heat Conduction Problem——the Study on the Synergy of Thermotechnical Parameters of Building External wall

The synergy of thermotechnical parameters of building external wall is related to inverse heat conduction problem and is a basic problem in heat transfer synergy theory. Its main purpose is to find the correlation among several parameters under a certain condition(such as a certain temperature field or heat flow flux). For this objective, the solution method of inverse problem is needed. Genetic algorithm is introduced and applied in this paper. A mathematic model is built in which the improved genetic algorithm is combined with numerical calculation. The verification is conducted by two case studies. It is found that the improved genetic algorithm can be used not only in the study of parameter synergy of steady conduction of building external wall, but also in the unsteady similar research.
