Nusselt Number Heat Transfer. Identification of the appropriate nusselt number correlations once the nature of convective heat transfer process has been recognized. In this context convection includes both advection and diffusion.
Complete any unfinished experiments from the flat plate heat transfer experiment from previous weeks 2. Nusselt number nu is the dimensionless parameter characterizing convective heat transfer. Where h convective heat transfer coefficient of the flow.
In heat transfer at a boundary surface within a fluid the nusselt number nu is the ratio of convective to conductive heat transfer across normal to the boundary.
Where h convective heat transfer coefficient of the flow. The average heat transfer coefficient is determined by the average nusselt number the inner diameter d of the pipe corresponds to the characteristic length. The cooling area is the sum of lateral fins surface and the plane surface as shown in fig. A variety of correlations are in use for predicting heat transfer rates in laminar flow.
