An improved form for natural convection heat transfer correlationsAdiutori, Eugene F. (Avtor)
heat transfernatural convectionNatural convection heat transfer correlations are usually in the form Nusselt{Rayleigh}, and occasionally in the form Nusselt{Rayleigh*}. 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 difference.Association of Mechanical Engineers and Technicians of Slovenia et al.20052015-07-10 18:52:16Delo ni kategorizirano60880UDK: 536.2ISSN pri Ä¨lanku: 0039-2480COBISS_ID: 8610075OceCobissID: 762116sl
