摘要

湍流多重态是近期湍流研究的热点问题。多重态是指在相同的控制参数下，湍流系统会出现不同的流动结构和统计特性。文章通过实验研究，分析了Rayleigh-Bénard 热湍流系统中的多重态现象以及湍流态与热输运的关系。首先借助粒子图像测速技术直接测量了偶极子流态和四极子流态的空间结构，结果表明通过温度场和速度场测量得到的大尺度湍流结构信息是一致的。通过流动结构和热输运同步测量发现热湍流中存在以不同大尺度湍流结构为典型特征的多重态现象，且高阶模态主导的湍流态的热输运效率高于低阶模态主导的湍流态，说明高对称性流态热输运效率高于低对称性流态，为通过调控大尺度湍流结构从而调控热湍流输运效率提供理论基础。随着热湍流控制参数Rayleigh数的增加，大尺度湍流结构会由高阶模态主导的流态演化到偶极子流态，这里偶极子流态对应于最低阶的流动模态。此外，研究中采用的圆环对流腔体会引入空间约束效应。进一步分析发现空间约束效应不仅会改变大尺度湍流结构的动力学特性，也会改变热湍流的热输运特性：当空间约束导致高阶模态主导的湍流态出现时，其会增强热湍流系统的热输运效率；反之，当空间约束导致低阶模态主导的湍流流态出现时，其则会抑制热湍流系统的热输运效率。

Abstract

The existence of multiple states characterized by different large-scale flow structures or different statistical properties in a turbulent flow has attracted lots of research interests. In this paper

we present an experimental study of multiple states and heat transport in turbulent thermal convection. The experiment was carried out in an annulus Rayleigh-Benard turbulence system with a Rayleigh number (

) range of 2×10

≤

≤ 2.9×10

and at a fixed Prand

tl number of

= 5.4. Consistent with the discovery by Xie

we show in a wider range of

that the large-scale flow bifurcates from a high-heat-transport efficiency state to a low-heat-transport efficiency state. Direct measurements of the flow structure using particle image velocimetry reveal that the large-scale flow in the high-heat-transport state shows a quadrupole structure

and the low-heat-transport state shows a dipole structure. In addition

it is found that the third and fourth flow modes are more efficient in heat transport when compared with the dipole and the quadrupole modes. This observation provides another evidence that the higher the symmetry of the flow

the higher the heat transport efficiency. When the large-scale flow is dominated by the dipole mode

it is showed that there is a preferred orientation which acts as a potential well. Further analysis shows that when the large-scale flow is trapped in this preferred orientation

its random azimuthal meandering is suppressed dramatically with increasing

. The annulus cell used in the present study will unavoidably introduce the spatial confinement effect. It is found that this spatial confinement not only changes the structure of the large-scale flow but also alters its dynamics. Whether spatial confinement leading to an enhanced or a reduced heat transport efficiency depends on the resulting large-scale flow modes

i.e.

when spatial confinement results in higher order flow modes

the heat transport efficiency is enhanced

otherwise reduced.
