- National standard “Measurement of Thermal Diffusivity or Thermal Conductivity by Flash Method”
Testing principle of Transient laser thermal conductivity analyzer, flash method, Diffusivity measuring instrument
- A thin sample is irradiated by a high-intensity short-time energy pulse. The front side of the sample absorbs the pulse energy to increase the temperature on the back side.
- The temperature change on the back side is recorded. After receiving the light pulse irradiation, the temperature on the back side of the sample rises to half of the maximum value. time (also called half-heating time), and use a computer to quickly calculate its thermal diffusion coefficient and thermal conductivity through a special mathematical model.
