Abstract

Many times complete knowledge of thermal transport properties is needed before the material can be employed in a thermal application. Pulsed video thermography (PVT) is an emerging nondestructive evaluation technique that in many cases offers advantages over well-established methods for thermal property measurements. It is an inexpensive, rapid, easily portable technique, suitable for use in manufacturing environments. In this paper, the fundamental theory behind the use of PVT for the simultaneous measurement of a solid material's local and global thermal diffusivity, thermal conductivity, specific heat, and surface heat transfer coefficient are given. Additionally, results obtained from the PVT method when applied to plates of carbon-carbon composites, low carbon steel, and plastic are compared to those obtained by traditional means.
