How Laser Pulses Measure Heat Flow

Description

Laser flash analysis measures thermal diffusivity, which describes how fast heat moves through a material compared with how much heat it stores. This material-specific property helps show how a sample transfers thermal energy and how it responds to temperature changes.

Thermal diffusivity is rela...

Transcript

Thermal diffusivity is an important property used to assess how a material transfers heat and reacts to changes in temperature. Thermal diffusivity, alpha, is the ratio of how much heat is conducted in a material relative to how much heat is stored. Similarly thermal conductivity, kappa, describes how much heat is transferred through a material ...
