A study has been conducted experimentally on the natural convection heat transfer characteristics of a horizontal flat plate with vertical rectangular fins in air.
The effects of fin heights and Rayleigh numbers are mainly investigated.
1. The mean fin and mean total Nusselt numbers increase as dimensionless fin heights increase at 0.67≤H/S≤ 1.67. But the mean plate Nusselt numbers decrease as dimensionless fin heights increase.
2. The mean fin surface Nusselt numbers has it's maximum outside surface (Y_2) where there is in terference from each other fin.
3. The mean Nusselt numbers increase as Rayleigh numbers increase.
4. The mean fin Nusselt numbers are 116% and 455% respectively more than the mean plate Nusselt numbers at H/S=0.67 and 1.67 for Ra_m=7.31×10^3
