The program NETZSCH
Thermal Simulations allows the simulation of the thermal
behavior of different materials. Main applications are
simulation of materials containing a high thermal potential
and estimation of thermal explosions, as well as estimation
of temperature overflow during the curing of epoxy
resins.
Considering the heat loss over the surface and thermal
conductivity inside the reactor, the following are included
in the equation as external boundary conditions:
- reactor type (infinite
plate, infinite cylinder, sphere),
- thickness or radius of the reactor,
- initial temperature inside the reactor T,
- ambient temperature Ta as temperature program,
- heat transfer coefficient from the surface into the
environment, k,
- thermal conductivity of the material (in dependence on the
temperature),
- density of the material (in dependence on the
temperature),
- specific heat capacity cv of the material (in dependence
on the temperature) and
- reaction heat H.
An expanded form of the
THOMAS model [1] is used to characterize the thermal
behavior (1):
This expansion concerns above all the function of heat
generation f(cj,t,T), where cj is the concentration of
formal reactants j, t the time and T the temperature. By
this expansion a fit to reality is managed to a great
extent.
