论文摘要
SCF实验是根据Egbers和Rath [Acta Mech的工作进行的。 111pp。125--140（1995）]。通过使用激光板照明的水平平面上漂移的铝制片，通过使用实验获得的相位速度和数值推导的比较相位，将流量鉴定为具有方位波数$ m = 3 $的螺旋波。通过求解在螺旋波流场中延伸的无穷小平面颗粒的运动方程，实际上可以重现反射光的视觉分布，这与实验获得的图片非常一致。
SCF experiments were conducted according to the work of Egbers and Rath [Acta Mech. 111 pp. 125--140 (1995)]. Through visualization using aluminium flakes drifting on a horizontal plane illuminated by a laser sheet, the flow was identified as a spiral wave with azimuthal wavenumber $m=3$, using the experimentally obtained and numerically deduced comparison between phase velocities. By solving the equation of motion for the infinitesimal planar particles advecting in the flow field of the spiral wave, a visual distribution of reflected light was reproduced virtually, which is in good agreement with the picture obtained experimentally.
