Determination of Thermal Diffusivity Values Based on the Inverse Problem of Heat Conduction – Numerical Analysis

Abstract This paper presents a discussion on the accuracy of method determining thermal diffusivity solids using solution inverse heat conduction equation. A new measurement data processing procedure was proposed to improve effectiveness method. Using numerical model, an analysis sensitivity determination changes in operational and environmental parameters test carried out. The obtained results showed that insensitive excitation impulse, thickness tested sample, significant influence convection cooling its accuracy. work completed with formulation general conclusions concerning conditions for materials use described
