Vibration-induced ‘anti-gravity’ tames thermal turbulence at high Rayleigh numbers

We report that vertical vibration with small amplitude and high frequency can tame convective heat transport in Rayleigh–Bénard convection a turbulent regime. When is applied, dynamically averaged ‘anti-gravity’ results stabilizes the thermal boundary layer inhibits eruption of plumes. This eventually leads to attenuation intensity large-scale mean flow significant suppression transport. Accounting for both thermally led buoyancy vibration-induced anti-gravitational effects, we propose an effective Rayleigh number helps extend Grossmann–Lohse theory vibrational turbulence. The prediction reduction on Nusselt Reynolds numbers obtained by extended model found agree well numerical data. In addition, influences structure temporal evolution are investigated. non-uniform characteristic discussed. present findings provide powerful basis studying turbulence put forward novel strategy actively controlling
