Thermal diffusivity is a measure of the speed at which heat propagates in a medium by conduction when the temperature varies with time. It is a thermophysical property whose value is directly ...

In this article, we discuss the laser flash diffusivity method’s working principle, applications, its advantages over other methods, and finally its limitations and research directed towards ...

Mountain permafrost is warming and thawing worldwide due to climate change, with ground temperature being a key control of ...

“However, to compare model predictions with empirical observations, one needs to study the diffusion equation in finite space. Despite the work of illustrious scientists such as Smoluchowski, Pólya, ...
