The process of achieving thermal equilibrium

In this example, we will consider the process of achieving thermal equilibrium in a closed thermal system. All types of heat transfer are involved in the process of heat transfer: convective, conductive and radiative heat transfer.

The system itself consists of three parallel connected thermal resistances and three elements responsible for heat transfer. The initial temperature of the thermal mass on the left side of the circuit is 400 K, on the right side of the system is 300 K.

The result of the simulation is the achievement of thermal equilibrium (equality of temperatures in all parts of the system).
