7. Appendix: calculation of thermal stabilization times
This paragraph is based on papers by B. CASSAGNE (University of Nantes) and J.F. HENRY (University of Reims).
7.1 Principle
The problem to be addressed involves the thermal approach to "thermally thin" bodies. This assumes that heat is transferred much more easily by conduction (within the body under consideration) than by convection and radiation to the outside.
During time evolution, the body temperature is considered uniform T (x, y, z, t ) º T (t ).
-
The criterion used to ensure that a body is thermally thin is the Biot number (Bi ) defined by :
