Seeking example of 2nd order thermal system.

Click For Summary
SUMMARY

This discussion centers on the exploration of second-order thermal systems, specifically the analogy between thermal capacity and electrical components. The participant references the textbook "Modeling and Simulation of Dynamic Systems" by Woods and Lawrence, which states that an analogy for flow storage, akin to inductance in electrical systems, does not exist in thermal systems. The inquiry highlights the limitations of extending electrical analogies to second-order thermal systems, emphasizing the need for a deeper understanding of thermodynamic principles.

PREREQUISITES
  • Understanding of thermodynamics principles
  • Familiarity with first-order and second-order systems
  • Basic knowledge of electrical components, specifically capacitors and inductors
  • Experience with modeling and simulation techniques in dynamic systems
NEXT STEPS
  • Research the characteristics of second-order thermal systems
  • Study the limitations of analogies between electrical and thermal systems
  • Explore advanced thermodynamic concepts related to heat transfer
  • Investigate modeling techniques for dynamic thermal systems
USEFUL FOR

Students and professionals in thermodynamics, engineers working with dynamic systems, and anyone interested in the limitations of analogies between electrical and thermal systems.

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."
