Seeking example of 2nd order thermal system.

[DragonPetter]

I'm not very experienced on heat laws and devices, other than general thermodynamics. But I am studying 2nd order systems, and the curiosity came up if there is a 2nd order thermo system, since my book only described a 1st order one.

I see the thermal capacity as an electronics capacitor, but what is the analogy to an inductor? Does this analogy only have so much limits on it to extend to 2nd order?

Any ideas appreciated :)

According to my old textbook (Modeling and Simulation of Dynamic Systems, Woods and Lawrence) an analogy for flow storage, i.e. inductance, for thermal systems "does not exist."
