New Transient Non-Destructive Technique Measures Thermal Effusivity and Diffusivity
Abstract
Thermal conductivity analysis and resultant data can be invaluable in helping to ensure consistent product quality. There are five main types of commercially available instruments to measure thermal conductivity: guarded hot plate, hot wire, modified hot wire, laser flash diffusivity and modulated differential scanning calorimetry (DSC). They differ in technique, sample size, testing time, capability, and methodologies of measurement. The sample size and test times of many techniques have positioned thermal conductivity analysis within the R&D operation, or to some extent, QA labs.
