Adiabatic surface

[szilagyics]

Hello All,

If I use in a SURF line ADIABATIC=.TRUE. the Obstruction will be
adiabatic. It's ok. I don't know what will be happen with the heat
which will arrive to my surface by radiation. It will be reradiation
or it will lose from my space.

Thank you for your attention,

adiabatic means 0 net heat transfer. Incoming radiative + convective
= outgoing radiative + convective

[szilagyics]

How can I determine a suface which glint the incoming heat perfectly?
I would like a surface which behave like a "mirror".

Thank you for your attention.

An adiabatic surface has no net heat transfer. The temperature of
the surface is set so that
h (T_gas - T_wall) + q_rad_in - emissivity_wall * stefan_boltzman *
T_wall^4 = 0

What do you mean behave like a mirror? Do you want convective heat
transfer but not radiative?

Sorry, my english is not enough good.

I would like that my surface won't be in reaction. I would like my
suface won't transport heat from the the site where is the fire. I
would like the surface reradiation all of heat which is arrived on the
surface. I would like the surface will be similar like a "mirror".

That is what adiabatic does. No heat transfer. If you want to reflect
radiation set emissivity to 0.
