Description
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.
Dialog Box and Parameters
- Area
Surface area of heat transfer. The default value is 0.0001 m^2.
- Radiation heat transfer coefficient
Heat transfer coefficient according to the Stefan-Boltzmann
law. The default value is 4e-8 W/m^2/K^4.
Ports
The block has the following ports:
- A
Thermal conserving port associated with body A.
- B
Thermal conserving port associated with body B.
