Sensor's thermal diffusivity

WebAug 23, 2024 · Thermal Diffusivity Formula. Thermal Diffusivity is mathematically stated as. α = k ρ c p. Where, α = Thermal Diffusivity of the material. k = Thermal conductivity of the material. ρ = Density of the material. C p = Specific heat capacity of the material. The dimensional formula of thermal diffusivity is [L2T-1]. WebThe most common way to measure thermal diffusifity will be the well known Laser flash method (LFA). Here a sample is pulsed with a Laser and an IR detector on the opposite detects the temperature rise of the sample, what leads to the thermal diffusifity.
