Hello, I'm slowly getting crazy about this stuff. I'm trying to understand what are thermal inertia/effusivity and information have been incoherent so far. The best example of that is seen on wikipedia where the only mention of thermal inertia is in the article
https://en.m.wikipedia.org/wiki/Volumetric_heat_capacity
However in the very section of thermal inertia the article refers to thermal effusivity with the same equation.
I've tried my university physics section but the books talks only about thermal conductivity ( not even thermal diffusivity ).
So far I understood that thermal inertia is akin to mechanical inertia. It is how the material is opposed to change its temperature. I understand that thermal effusivity is how the material exchange heat with its environment. However I don't understand what are their respective equations and why oh god why is it so hard to find information about those concepts.
So here am I humbly asking for helps.
Thanks in advance!
ps: I'm not sure that I posted in the right section : /Edit: two scientific article talking about either effusivity or inertia with the same formula
