- Abstract
- This investigation determines the convective heat transfer coefficient from the vertical, warm walls of a refrigerator which has cold contents. The influence of enclosure height and contents configuration on the magnitude of the coefficient is established. The heat transfer data are correlated with three different models. The first is a simple power law relating the Nusselt number to the Rayleigh number. The other correlations include the effect of the contents configuration by adding a geometric parameter which is either an area or a volume ratio of the contents to the enclosure. All three correlations yield a coefficient of determination greater than 0.93. The Rayleigh number based on the enclosure height and the temperature difference between the enclosure and the contents ranges from 4.8 x 106 to 6.1 x 108. The surface area ratio varies from 0.47 to 0.91, while the volume ratio varies from 0.11 to 0.32.
