WebNusselt number. In thermal fluid dynamics, the Nusselt number ( Nu, after Wilhelm Nusselt [1] : 336 ) 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 ...

WebJan 1, 2024 · As the planar ESAs are usually limited in the bandwidths and the efficiencies because of the small volume occupation of the Chu-sphere, the spatially integrated ESAs, such as hemispherical ESA, can ideally occupy the Chu-sphere, thereby offering substantially improved performance. WebFigure 2.1: Chu Sphere of radius "a" [1] Hansen in [4] proposed another generally agreed upon de nition for an ESA that satis es the condition ka<1. In other words, it is surrounded by a sphere whose radius is one "radianlength". This sphere, called the "radiansphere" [5] sets a border between the near- and far- eld radiation of a Hertzian dipole.
WebAlternatively, Chu [2] defined the ESA as an antenna that satisfies the condition– <0.5 Where k is the wavenumber(2π/λ), and ais the radius of the minimum size sphere that encloses the antenna. This is commonly referred to as the “Chu sphere” and is shown in Figure 1. Figure 1- Chu sphere of radius 'a' centered about the origin. [5] WebarXiv.org e-Print archive
