Thermal Diffusivity

Thermal diffusivity

is a measure of how quickly heat spreads through a material. It combines three fundamental properties of materials: thermal conductivity, density, and specific heat capacity. Essentially, thermal diffusivity tells us how fast a material can change temperature when exposed to heat. Thermal diffusivity can be measured using several methods, including laser flash analysis, hot wire technique, and transient plane source technique. Each method offers different advantages depending on the type of material and the precision required. Whether you are involved in product design, industrial processes, or energy management, understanding thermal diffusivity can provide a competitive edge. By choosing the right materials with the appropriate thermal properties, you can enhance the safety, performance, and energy efficiency of your products and systems.
