Abstract
This paper presents an experimental method for obtaining, simultaneously, thermal properties of solid materials using genetic algorithm (GA). The experimental method is based on the use of a surface probe that has one resistance heater, two thermocouples and one heat flux sensor. The technique relies on the minimization of multi-objective function with a quadratic error between measured and mathematical temperatures in same specific positions. Green’s functions are used to determine analytical solution of temperature which is compared with the experimental measured, with that comparation we estimate thermal conductivity and thermal diffusivity.
