ABSTRACT

Measurements were performed to determine the average natural convection heat transfer characteristics for an isothermal, upward-facing horizontal constrained rectangular plate, i.e. surrounded (fenced) by vertical adiabatic walls. Results revealed that for the Rayleigh number ranged from Ra = 1.8×106 to 1.5×107 and relative height of the walls in the range from about H/W = 0.25 to 1.0 the average Nusselt number is described with the equation Nu=0.458 Ra0.271. These results are higher in comparison with the data obtained for an isothermal horizontal plate in semi-infinite surface by about 15 to 18% in laminar region and 12 to 11 % in turbulent region. The aspect ratio of the rectangular plate was Y/W=2.548.
