对流槽宽高比对长方体湍流热对流系统传热影响的实验研究
spect-ratio dependence of heat transport by turbulent Rayleigh-Bénard convection in rectangular cells
本文采用长方体对流槽，实验研究了以水为流体介质的Rayleigh-Bénard湍流热对流系统中对流槽宽高比对系统湍流传热Nu-Ra关系的影响。与圆柱形对流槽中的情形不同，我们的结果表明在长方体对流槽中系统湍流传热的Nu-Ra关系几乎独立于系统对流槽的宽高比。
In this paper, we report high-precision measurements of the Nusselt number Nu as a function of the Rayleigh number Ra in water-filled rectangular Rayleigh-Bénard convection cells. Our results show that unlike the situation in the cylindrical cells, the turbulent heat transport in the rectangular cells are nearly independent of the cells' aspect ratios.
