Two dimensional heat transfer<br />
Outside<br />
Inside<br />
• Transmission / conduction is<br />
one dimensional far from a<br />
corner but progressively<br />
shows two dimensional<br />
characteristics close to the<br />
corner.<br />
• One dimensional analysis<br />
tends to overestimates heat<br />
loss in the case <strong>of</strong> a convex<br />
corner and underestimates in<br />
the case <strong>of</strong> a concave corner<br />
(if external dimensions are<br />
used)<br />
• Two dimensional analysis<br />
has to be used in order to<br />
accurately predict heat<br />
transfer.<br />
