Information
The following bLloyd and Moran correlation is applicable for an horizontal plate in rest environment (no forced convection) where the fluid is bellow the wall. The formula is picked from the ASHRAE guide chapter 3 table 10 equation T10.5 to T10.9
The correlation is given for a Rayleigh number:
- 105 < Ra < 1010 for a Downward-facing heated plate
- 1 < Ra < 109 for a Downward-facing cooled plate
Where :
- Nu is the Nusselt number
- Ra is the Rayleigh number
