RT 2012 - The use of RC (resistor-capacitor) scheme in thermal behavior study of a group

We were able to establish the set of equations for the RC model, and to do so we made a few assumptions.

• Corrected radiative exchange coefficient h_rs

  To establish the value of h_ri and then of h_rs, assume that :

  • wall emissivity is 0.9 ;

  • the ratio of the area of heavy walls to the area of light walls is 2.5/2 ;

  • radiation is carried out with an additional surface area of 20%.

• Model development

  The initial model is based on 3 nodes: air, light walls and heavy walls. The 3 nodes have convective and radiative exchanges between them. The heavy walls are the only ones with thermal inertia.
