温度拡散率
1. Thermal diffusivityIn heat transfer analysis, thermal diffusivity (usually denoted α but a, κ, k, and D are also used) is the thermal conductivity divided by density and specific heat capacity at constant pressure. It has the SI unit of m²/s. The formula is: where is thermal conductivity (W/) is density (kg/m³) is specific heat capacity (J/) The denominator can be considered the volumetric heat capacity (J/). In a sense, thermal diffusivity is the measure of thermal inertia.
