Figure 4.
The diagram represents a cylindrical heat transfer model. It shows a vertical section with a core at the centre surrounded by a can, and a mandrel along the left boundary at radius equals zero. Heat generation is indicated within the core, and arrows point outward from the surface, representing convective heat flux directed to the surroundings. The convective heat transfer term is shown as heat flux multiplied by the normal vector. The core and can are labelled, illustrating radial heat transfer from the interior to the external environment.Schematic representation of thermal model computational domain, of the components and of the applied boundary condition
