摘要

Rayleigh-Bénard对流单元中大尺度环流的时间相关行为表现出一组丰富的不同三维流动特征，如旋转或扭转模式。在本文中，数值研究了非接触感应流层析成像在填充GaInSn的圆柱形细胞中可视化这些流动特征的适用性。直径为320毫米、高度为640毫米的圆柱体中的模拟流动是研究非接触感应流断层扫描重建速度场质量的基础。图5，参考文献9。

Flow reconstruction in a Rayleigh-Bénard convection cell with an aspect ratio 0.5 by contactless inductive flow tomography

The time dependent behaviour of the large-scale circulation in a Rayleigh-Bénard convection cell exhibits a rich set of different three-dimensional flow features like rotations or torsional modes. In this paper, the applicability of contactless inductive flow tomography to visualise these flow features in a cylindrical cell filled with GaInSn is investigated numerically. The simulated flow in the cylinder with a diameter of 320 mm and a height of 640 mm serves as a basis to investigate the quality of the reconstructed velocity field by contactless inductive flow tomography. Figs 5, Refs 9.
