General
The heat radiation from an aluminum plate is analyzed.
The heat transfer coefficient is acquired manually.
To acquire it automatically, see “Exercise 14: Natural Convection with Correction Coefficient Automatically Calculated”.
The temperature distribution and the heat flux vectors are solved.
Unless specified in the list below, the default conditions will be applied.

Aluminum plate, defined by a rectangular solid body, is placed vertically. The bottom face is set with the Temperature boundary condition.
The other faces are set with the Heat transfer/Ambient radiation boundary condition.

The coefficient for the natural convection is given by the formula below. See [Heat Transfer/Ambient Radiation] for more information.
The coefficient can be calculated automatically if that is preferred.
2.51×C×(1/L)^(1/4) = 2.50 [W/m2/deg5/4]
where
C = 0.56
L = 0.1

The temperature distribution is shown below.
The temperature is 80[deg] at the bottom face and it decrease gradually to 72[deg] at higher places.
The vectors of the heat flux are shown below.
Heat flux vectors point from higher temperature towards lower temperature. Their magnitude indicates the temperature gradient.
