Thermal diffusivity - Wikipedia

In heat transfer analysis, thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure. It measures the rate of transfer of heat of a material from the hot end to the cold end. It has the SI derived unit of m /s. Thermal diffusivity is usually denoted by lowercase alpha (α), but a, h, κ (kappa), K, and D are also used. The formula is: WebToggle the table of contents. Diffusivity. 7 languages. ... Diffusivity is a rate of diffusion, a measure of the rate at which particles or heat or fluids can spread. It is measured differently for different mediums.
