WebThe Flash Method determines the thermal diffusivity. Using a suited reference material, it is also possible to measure the specific heat capacity in a comparative method. The thermal … The laser flash analysis or laser flash method is used to measure thermal diffusivity of a variety of different materials. An energy pulse heats one side of a plane-parallel sample and the resulting time dependent temperature rise on the backside due to the energy input is detected. The higher the thermal diffusivity of the … See more The laser flash method was developed by Parker et al. in 1961. In a vertical setup, a light source (e.g. laser, flashlamp) heats the sample from the bottom side and a detector on top detects the time-dependent … See more • Physics portal • Thermal conductivity • Thermal conductivity measurement • Thermal diffusivity • Thermal physics See more
