The flash method, first described by W.J. Parker et. al in 1961, is a widely used technique for measuring the thermal conductivity of materials. Our Flash Method demo app, highlighted here, performs a numerical simulation of this experiment, offering a simplified approach to modifying parameters that can impact its overall accuracy. Today, we’ll take a closer look at this easy-to-use app, as well as the theory behind it.

Radiators, refrigerators, and geothermal pumps all need to efficiently extract heat from one fluid to another without mixing them. Among all of the different heat exchanger designs, finned pipes aim to increase the exchange surface between the content of a pipe and the exterior using fins. Finned pipes usually show a geometrical periodicity along the length, which we will take advantage of in this demo app to reduce computational costs.

In a previous blog post, we presented the applications of conjugate heat transfer involving immobile solids. The case of immobile solids simplifies the heat equation to be solved and is often a good approximation to the temperature field. Today, we will complete the description of the physics that account for thermoelastic effects of the material when heat transfer and solid mechanics are coupled.
