Large-scale Structure in Rayleigh-BCnard Convection with Impenetrable Sidewalls
نویسندگان
چکیده
In numerical Rayleigh-BCnard convection at Rayleigh number lo5 and 5 x 105, Prandtl numbers 0.07, 0.7, and 7, and aspect ratios 3, 4 or 6, large-scale patterns are sought. For aspect ratio 6 and Pr = 0.7, saturation of the mean velocity is only observed after 20 convective timescales. Three-dimensional visualization shows a strong influence of the confining sidewalls and corners for all Prandtl numbers. Sweeping motions are observed for Pr = 7.

متن کاملTraveling Waves in Axisymmetric Convection: the Role of Sidewall Conductivity
The results of a full numerical simulation of Rayleigh-Brnard convection in a cylindrical container of aspect ratio five are reported. Near onset, convection takes the form of five concentric rolls, which in fluids of moderate to large Prandtl number, are stable to nonaxisymmetric perturbations. As the Rayleigh number is increased, these ,,oils are succeeded by traveling waves when the sidewall...
متن کاملExtreme multiplicity in cylindrical Rayleigh-Bénard convection. I. Time dependence and oscillations.
Rayleigh-Bénard convection in a cylindrical container can take on many different spatial forms. Motivated by the results of Hof [Phys. Fluids 11, 2815 (1999)], who observed coexistence of several stable states at a single set of parameter values, we have carried out simulations at the same Prandtl number, that of water, and a radius-to-height aspect ratio of two. We have used two kinds of therm...
متن کاملBifurcation analysis of steady Rayleigh–Bénard convection in a cubical cavity with conducting sidewalls
Natural convection in a cubical cavity heated from below with perfectly conducting sidewalls is investigated numerically. A parameter continuation procedure based on a Galerkin spectral method was applied to obtain the bifurcation diagrams for steady flow solutions over the region of Rayleigh numbers Ra 1.5× 10 at Prandtl numbers Pr =0.71 and 130. In both cases, the bifurcation diagrams were mo...
متن کاملFinite Volume Simulation of Natural Convection in a Trapezoidal Cavity Filled with Various Fluids and Heated from the Top Wall
Laminar natural convection in a trapezoidal cavity filled with various fluids is studied numerically using a finite volume method. The cavity inclined left and right sidewalls are maintained at constant cold temperature while the top wall is maintained at constant hot temperature. The bottom wall is considered adiabatic. Fluid flow fields , isotherm patterns and the average Nusselt number are p...
