Purpose
of the program:
This programs calculates the time dependent temperature distribution in a layered
structure as a function of time.
The considered geometry is one-dimensional.
The
program is primarily written in view of the
calculation of fires, but is also suitable for use at much lower temperatures.
At the
left side of the first layer a prescribed heat source
is present during a certain time.
There
are THREE possibilities present for the input of the conditions at the LEFT and
RIGHT side:
1. Input of the air temperature [°C]
2.
Input of the incoming radiation [kW/m2]
3. Combination of point 1. and 2.
At point
1. next to air temperature
the heat transition coefficient has to be given [W/m2 °C]
For
point 2. the first layer is radiating somewhat
backwards as a consequence
of the raise in temperature and therefore
lowering the temperature somewhat (especially at
higher surface temperatures).
For
option 3. the amount of energy is put into the
structure by convection as well as radiation.
In the
various layers heat transport takes place by convection only.
It is
possible, when water is present, to limit the temperatures to a maximum of 100
degrees Celsius.
In a
possible cavity heat transport is only calculated by
means of radiation.
The
output of the calculations results is possible in numerical as well as
graphical form.
