Abstract
An experimental-computational hybrid system for measurement of thermal conductivity of orthotropic materials is developed. The system consists of two experimental parts and a finite element analysis part. Firstly, a temperature distribution generated by an uniform heating is measured with a thermal video system, and a thermal conductivity of Z direction is calculated. Secondary, a temperature distribution generated by a small area heating is measured with the system. In the final step, thermal transfer analyses simulated the experiment support efficient data, and thermal conductivity of in-plane directions are estimated by comparing between experimental and analytical temperature distributions. The orthotropic equivalent thermal conductivity of honeycomb materials given by this system agreed with the theoretical values.
