BIOT NUMBER
Biot number is proportional to { (thermal internal resistance) / (surface film resistance) } and is used in heat transfer in general and unsteady state calculations in particular. It is normally defined in the following form :
Where: |
delta-x |
= |
Mid-plane distance |
h_T |
= |
Heat transfer coefficient |
k |
= |
Thermal Conductivity |
