Thermal diffusivity: Definition, Formula, Units, Importance [with Pdf]

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: WebDefinition of Thermal Diffusivity. Thermal diffusivity ( a with the unit mm2/s) is a material-specific property for characterizing unsteady heat conduction. This value describes how quickly a material reacts to a change in temperature. In order to predict cooling processes or to simulate temperature fields, the thermal diffusivity must be known ...
