A novel system using supergravity opens a new avenue on the exploration of high–Rayleigh number thermal turbulence. High–Rayleigh number convective turbulence is ubiquitous in many natural phenomena and in industries, such as atmospheric circulations, oceanic flows, flows in the fluid core of planets, and energy generations. In this work, we present a novel approach to boost the Rayleigh number in thermal convection by exploiting centrifugal acceleration and rapidly rotating a cylindrical… 
Evidences for the existence of the ultimate regime in supergravitational turbulent thermal convection
What is the final state of turbulence when the driving parameter approaches to infinity? For thermal turbulence, in 1962, Kraichnan proposed a so-called ultimate scaling dependence of the heat
Ekman Layer Scrubbing and Shroud Heat Transfer in Centrifugal Buoyancy-Driven Convection
This paper presents large-eddy and direct numerical simulations of buoyancy-driven convection in sealed and open rapidly rotating cavities for Rayleigh numbers in the range 107–109, and axial
Experimental Study of Thermal Convection in a Cylindrical Layer with a Longitudinal Partition at Modulated Rotation
Thermal convection of a liquid in a simply connected horizontal cylindrical layer rotating at a variable velocity is investigated experimentally. The inner boundary of the layer has a higher
Coriolis effect on centrifugal buoyancy-driven convection in a thin cylindrical shell
Abstract We study the effect of the Coriolis force on centrifugal buoyancy-driven convection in a rotating cylindrical shell with inner cold wall and outer hot wall. This is done by performing direct

This paper addresses limitations of widely used Reynolds-averaged turbulence models (RANS) for prediction of gas turbine internal air systems. Results from direct numerical simulation (DNS),
Water entry of spheres into a rotating liquid
Abstract The transient cavity dynamics during water entry of a heavy, non-rotating sphere impacting a rotating pool of liquid is studied experimentally, numerically and theoretically. We show that
Effects of radius ratio on annular centrifugal Rayleigh–Bénard convection
Abstract We report on a three-dimensional direct numerical simulation study of flow structure and heat transport in the annular centrifugal Rayleigh–Bénard convection (ACRBC) system, with cold inner


Experimental and numerical investigation of turbulent convection in a rotating cylinder
The effects of an axial rotation on the turbulent convective flow because of an adverse temperature gradient in a water-filled upright cylindrical vessel are investigated. Both direct numerical
Turbulent convection at very high Rayleigh numbers
Investigating thermal transport over eleven orders of magnitude of the Rayleigh number, using cryogenic helium gas as the working fluid, finds no evidence for a transition to the Ra1/2 regime, and studies the variation of internal temperature fluctuations with Ra, and probe velocity statistics indirectly.
Sloping convection in a rotating fluid
Abstract Laboratory experiments on thermal convection in a fluid which rotates about a vertical axis and is subject to a horizontal temperature gradient show that when the rotation rate Ω exceeds a
Onset of convection induced by centrifugal buoyancy in a rotating cavity
Flows induced by centrifugal buoyancy occur in rotating systems in which the centrifugal force is large when compared to other body forces and are of interest for geophysicists and also in
Convection in the earth's mantle: towards a numerical simulation
Plate tectonics provides a remarkably accurate kinematic description of the motion of the earth's crust but a fully dynamical theory requires an understanding of convection in the mantle. Thus the
Scaling in thermal convection: a unifying theory
A systematic theory for the scaling of the Nusselt number Nu and of the Reynolds number Re in strong Rayleigh–Bénard convection is suggested and shown to be compatible with recent experiments. It
Heat transfer and large scale dynamics in turbulent Rayleigh-Bénard convection
The progress in our understanding of several aspects of turbulent Rayleigh-Benard convection is reviewed. The focus is on the question of how the Nusselt number and the Reynolds number depend on the
Multiple scaling in the ultimate regime of thermal convection
Very different types of scaling of the Nusselt number Nu with the Rayleigh number Ra have experimentally been found in the very large Ra regime beyond 1011. We understand and interpret these results
Search for the "ultimate state" in turbulent Rayleigh-Bénard convection.
Turbulent convection in a fluid heated from below and cooled from above is an important process in many geo- and astro-physical processes with typical Rayleigh numbers RaH1020. It has been

An investigation is described of the hydrodynamical flow that ensues when a liquid which rotates uniformly at O about a vertical axis is subject to a horizontal temperature gradient. Although O was
