In this study, experiment was carried out for Taylor-Couette vortex flow between a rotating inner cylinder and a fixed outer cylinder with small aspect ratio. It is two concentric rotating cylinders with a 25mm gap in aspect ration 3 and radial ratio 0.375 by mean of an ultrasonic velocity profiler (UVP). Successive instantaneous and mean velocity profiles were obtained by an ultrasonic Doppler velocity profile method, and the spatio-temporal velocity field had been the four-cell mode, N-2Cell, N-4Cell, A-3Ce11 and A-4Cell mode.
