Description: A Nusselt number of value one represents heat transfer by pure conduction. A value between one and 10 is characteristic of slug flow or laminar flow. A larger Nusselt number corresponds to more active convection, with turbulent flow typically in the 100–1000 range.

Description: The Nusselt number is a dimensionless number, named after a German engineer Wilhelm Nusselt. The Nusselt number is closely related to Péclet number and both numbers are used to describe the ratio of the thermal energy convected to the fluid to the thermal energy conducted within the fluid. Nusselt number is equal to the dimensionless temperature gradient at the surface, and it provides a ...

Description: Calculation of the Nusselt number for flat plates Laminar flow. For Reynolds numbers smaller than 10,000 and Prandtl numbers between 0.6 and 2000, the average Nusselt number for a laminar flow around a flat plate which is isothermally heated or cooled can be calculated using the following formula: \begin{align} \label{nul}

Description: The Nusselt number in the fully developed laminar flow is constant and depends on the channel geometry and the wall heat transfer boundary condition. Table 3.1 presents the Nusselt numbers for commonly used geometries under axially constant heat flux and circumferentially constant wall temperature (H1) boundary conditions with four-sided heating.

Description: Qualitatively, the Nusselt number development for other channel flows with heated walls is the same as for Poiseuille flow (regardless of geometry, turbulent flow, presence of scattering, nongrayness, etc.). The heat transfer behavior is somewhat different if a hot fluid enters a cold-walled duct (T w < T i).This is shown in Fig. 21-13 for turbulent tube flow of a gas seeded with small ...

Description: The laminar Nusselt number also depends on the heat transfer make up of the flow. For instance, it's 4.36 with a state of constant heat flux along the length of passage and 3.66 for constant wall temperature, and that's because the shape of the temperature profile is different for these different conditions.

Description: A Nusselt number close to one, namely convection and conduction of similar magnitude, is characteristic of "slug flow" or laminar flow. A larger Nusselt number corresponds to more active convection, with turbulent flow typically in the 100–1000 range.
