Natural Convection Correlations

Nusselt number correlations for natural (free) convection heat transfer. Covers vertical plates, horizontal plates (hot side up/down), horizontal cylinders, vertical cylinders, spheres, inclined plates, and enclosed cavities (vertical and horizontal). Each record provides the Nu correlation equation, valid Rayleigh number range, C and n coefficients (for power-law forms), characteristic length definition, Prandtl number range, and source reference. 30 records spanning all standard geometries from Churchill-Chu, Morgan, McAdams, Globe-Dropkin, Berkovsky-Efimov, Catton, and Hollands correlations.
