Alongside natural convection, thermal radiation, and thermal conduction it is one of the methods of heat transfer and allows significant amounts of heat energy to be transported very efficiently.
WebIn 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. In this context, … Webfor the calculation (Figure 4.3). Potential flow theory gives the velocity distribution outside the boundary layer: u∞(x) U =2sin()xR [4.3] However, separation has a significant effect on the flow on the upstream side of the cylinder and the following law is closer than [4.3] to the actual velocity distribution near the cylinder surface:
