WebNusselt number, and we note other advantages that compel (1.1) as the best definition of a horizontal-convective Nusselt number. Section4discusses the transient adjustment of Nu in (1.1) to its long-time average and introduces a ‘surface Nusselt number’, Nu s, that is defined in terms of the entropy flux through the top surface. WebThe Nusselt number is named after a German engineer Wilhelm Nusselt. The conductive component is measured under the same conditions as the heat convection but with …
WebIn fluid dynamics, the Nusselt number (Nu) is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection (fluid motion) and diffusion (conduction). The conductive component is measured under the same conditions as the convective but for a hypothetically motionless fluid.

WebThe Nusselt number is a dimensionless number used to describe the ratio of the thermal energy convected to the fluid to the thermal energy conducted within the fluid. For fully developed (hydrodynamically and thermally) turbulent flow in a smooth circular tube, the local Nusselt number may be obtained from the well-known Dittus-Boelter equation. blackthorns helmAn understanding of convection boundary layers is necessary to understanding convective heat transfer between a surface and a fluid flowing past it. A thermal boundary layer develops if the fluid free stream temperature and the surface temperatures differ. A temperature profile exists due to the energy exchange resulting from this temperature difference.
