WebNov 15, 2024 · In addition, we also provide an instability criterion, under which the magnetic Rayleigh-Bénard problem is unstable. This instability result shows that the thermal instability still occurs when the (impressed) magnetic field is weak. Bio. 江松,北京应用物理与计算数学研究所研究员。

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 ... In fluid thermodynamics, Rayleigh–Bénard convection is a type of natural convection, occurring in a planar horizontal layer of fluid heated from below, in which the fluid develops a regular pattern of convection cells known as Bénard cells.
