WebFeb 17, 2024 · Le nombre de Rayleigh est utilisé pour exprimer le transfert de chaleur en convection naturelle. L’amplitude du nombre de Rayleigh est une bonne indication pour savoir si la couche limite de convection naturelle est laminaire ou turbulente. Les corrélations empiriques simples pour le nombre moyen de Nusselt, Nu, en convection … Le nombre de Rayleigh () est un nombre sans dimension utilisé en mécanique des fluides et caractérisant le transfert de chaleur au sein d'un fluide : inférieur à une valeur critique de l'ordre de 1 700, le transfert s'opère uniquement par conduction, tandis qu'au-delà de cette valeur la convection libre ou naturelle devient prépondérante. Ce nombre porte le nom de Lord Rayleigh, physicien anglais.

WebThe Rayleigh integral can be used for inverse acoustics as follows. Given a source radiating sound to a finite number of sensors, named the field (see figure 1(b)), one can define an infinite virtual plane between the source and the field. One can regard th e virtual plane, rather than the physical source, as the radiator of sound. song about youWebJohn William Strutt, 3r Baró de Rayleigh fou un professor universitari i físic anglès guardonat amb el Premi Nobel de Física el 1904.
