The Influence of Drilled Cavities on Natural Convection Heat Transfer from a Horizontal Surface.
Abstract
The objective of this project was to study the effect that small artificial cavities have on natural convection from a horizontal surface. Tests were run with water and Freon 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 O'Connor. Experimental results are presented for the heat transfer from horizontal circular disks, with and without artificial cavities.
