WebRayleigh-Bénard convection. This invaluable book presents a concise but systematic account of the formation of spatial flow structures in a horizontal fluid layer heated from below. Flows of this type, known as Rayleigh-Bénard convection, show important features of behaviour inherent not only in various hydrodynamic-instability phenomena but ... WebLa convection naturelle apparait largement dans la nature, et demeure un sujet d’intérêt majeur pour la compréhension des phénomènes géophysiques. Les écoulements qui lui sont liés sont de grande ampleur et restent difficiles à reproduire en laboratoire. Afin d'atteindre en laboratoire des régimes semblables, on se propose d'utiliser des fluides dont la …
