The Influence of Artificial Cavities on Natural Convection Heat Transfer from a Horizontal Surface.
Abstract
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 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 in previous investigation. Experimental results are presented for the heat transfer from horizontal circular disks, with and without artificial cavities.
