Both forms are inconvenient because they oftentimes require indirect solution: - When Nusselt{Rayleigh} correlations are used to calculate heat flux, solution is simple and direct. But when they are used to calculate boundary layer temperature difference, solution must be indirect-i.e. must be based on an indirect method such as iteration or trial-and-error. - When Nusselt{Rayleigh*} correlations are used to calculate boundary layer temperature difference, solution is direct. But when they are used to calculate heat flux, solution must be indirect. This manuscript describes an improved form for natural convection heat transfer correlations. The improved form allows direct solution for heat flux and for boundary layer temperature differenceTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
