振動格子乱流における弱い回転による二次流れ抑制の検討

内田晃一　山田格　森西洋平

Fundamental understanding of the flow structure of the rotating turbulence generated by an oscillating grid plays a crucial role in better climate predictions and enhancement of fluid machinery performance. In the experiment, however, turbulence statistics are often influenced by secondary flows inherently arising in a tank particularly under large oscillation conditions. In this study, we aim at suppressing the secondary flow by rotating the tank with small rotation speed. The flow field of the oscillating grid turbulence in a tank with a small rotation speed are visualized and measured with the PIV technique. The effect of the rotation speed on the secondary flow suppression is investigated by the analyzed PIV data.
