Abstract
AbstractConvective heat and mass transfer rates for 20 shapes suspended in various orientations in a hot turbulent air stream were correlated by the equation: for turbulent intensities between 9 and 10%, using a new characteristic dimension, L”, in the Reynolds Number. This dimension, defined as the total surface area divided by the maximum perimeter perpendicular to flow, was qualitatively explained from boundary layer considerations and was found to correlate the data for different shapes available in the literature. Qualitative pictures for the relative rates of heat and mass transfer around the various shapes were also obtained.
