Rayleigh convection
WebJul 1, 2024 · The Rayleigh–Bénard convection in a cylindrical container has received extensive attention because of its theoretical and practical applications [3, 4]. Moreover, being simple in geometry while exhibiting rich nonlinear dynamical behavior, the cylindrical Rayleigh–Bénard convection is a classic prototype for studying pattern formation. WebMar 29, 2006 · The average roll diameter in Rayleigh convection for 2000 < R < 31000, where R is the Rayleigh number, has been measured from photographs of three convecting fluids: air, water and a silicone oil with a Prandtl number σ of 450. For air the average dimensionless roll diameter was found to depend uniquely upon R and to increase …

WebApr 11, 2024 · Here we investigate experimentally the complete freezing process of water with dissolved salt in a standard natural convection system, i.e. the prototypical Rayleigh–Bénard cell. Due to the presence of a mushy phase, the studied system is considerably more complex than the freezing of fresh water in the same conditions (Wang … WebApr 20, 2000 · Turbulent convection occurs when the Rayleigh number (Ra)—which quantifies the relative magnitude of thermal driving to dissipative forces in the fluid motion—becomes sufficiently high.
WebJul 29, 2024 · Rayleigh–Bénard convection (RBC) provides a widely studied paradigm for thermally driven flows, which are ubiquitous in nature and in industrial applications [ 1 ]. Buoyancy effects, ultimately yielding to fluid dynamics instability, are determined by temperature gradients [ 2] and impact on the heat transport.
