Nusselt Numbers in Rectangular Ducts With Laminar Viscous Dissipation
Journal of Heat Transfer, 1999In this paper, the steady temperature distribution and the Nusselt numbers are analytically determined for a Newtonian incompressible fluid in a rectangular duct, in fully developed laminar flow with viscous dissipation, for any combination of heated and adiabatic sides of the duct, in H1 boundary condition, and neglecting the axial heat conduction in ...

A New Correlation of Nusselt Number for Impinging Jets
Heat Transfer Engineering, 2009Jet impingement heat transfer has received a remarkable amount of attention by researchers throughout the world for many years due to widespread interest from both academic and industrial points of view. However, the fluid dynamics involved with arrays of jets are very complex and still not completely understood. Therefore, a functional relationship of

Nußelt-Zahl Nu (Nusselt number Nu)
2000Es handelt sich um eine dimensionslose Kennzahl im Sinne der Dimensionsanalysis. Sie wird haufig zur dimensionslosen Darstellung des Warmeuberganges in der Form Nu = Nu(⋯) benutzt und stellt in diesem Sinne eine Zielkennzahl dar (dimensionslose Form einer gesuchten Grose, hier der Wandwarmestromdichte).
