Description: The objective of this project was to study the effect of small artificial cavities on natural convection from a horizontal surface.  Tests were run with Feron 113.  Data for heat flux as a function of bulk temperature difference were carefully obtained.  These data yielded Nusselt number as a function of Grashof number or Rayleigh number.  All of these were then compared with the data obtained by Hiep [Ref. 2].  Experimental results are presented for the heat transfer from horizontal circular disks, with and without artificial cavities.  The artificial cavities were found to affect the natural convection heat transfer from a horizontal surface: the heat transfer coefficients increased with the number of cavities.
