Thermal Elements
The Radiative Heat Transfer block represents a heat transfer by radiation between two surfaces in such a way that the energy of emitting body is completely absorbed by a receiving body. The transfer is governed by the Stefan-Boltzmann law and is described with the following equation:
where
| Q | Heat flow |
| k | Radiation heat transfer coefficient |
| A | Surface area |
| TA,TB | Temperatures of the bodies |
Connections A and B are thermal conserving ports associated with the emitting and receiving bodies, respectively. The block positive direction is from port A to port B. This means that the heat flow is positive if it flows from A to B.
Surface area of heat transfer. The default value is 0.0001 m^2.
Heat transfer coefficient according to the Stefan-Boltzmann law. The default value is 4e-8 W/m^2/K^4.
The block has the following ports:
Thermal conserving port associated with body A.
Thermal conserving port associated with body B.
