【Abstract】 A new method for measuring steady two-dimensional flow field using onedimensional Laser Doppler Velocimeter system is first presented in this paper. As an application of the technique, the two-dimensional time-averaged velocity distributions of the steady free flow upstream of a vertical planar sluice gate are measured and satisfactory results are obtained.更多还原
