The flash method is widely used for measuring the thermal conductivity of a thin sample material that is about the size of a coin. The sample material is submitted to a laser pulse on one of its faces. In turn, the opposite face is heated up by around 1 K. As the pulse is uniform and well defined, you can measure the temperature variation on the other side. Thereby, you can measure the thermal conductivity of the sample with high accuracy.

The Flash Method simulation app reproduces the real-world experiment and provides options to define experiment parameters that can affect the accuracy of the method and your experiment. This means that you can specify sample height, radius, and material. You can also set the ambient temperature, enable or disable convection and radiation effects, and customize the values of the heat transfer coefficient and the surface emissivities of both the sample and the enclosure.
