<DIV><FONT face=Arial size=2>Hye Ahmed,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Last month, I have study the possibilities to
change the emissivity of the internal walls in TYPE 56. But, TYPE 56 fixes the
emissivity to 1 for the internal walls and the view factor is equal to the ratio
of the emitted areas.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>You can tuned the surface emissivity of the
internal walls by changing the Tmean value in PreBid in order to compensate the
effect of a change of emissivity. This change has an effect on all heat
transfers by radiation.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In attachment, you will find a repport (project
IEA34/43) which gives you more details.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Bye.</FONT></DIV>
