The turbulent characteristics,including turbulence intensity,gust factor,integral length scales and wind spectrum,were summarized based on a large amount of measured data,and compared with Code ones.

The conceptual experiment has been done in a flume,and the three-dimensional ultrasonic Doppler speedometer ADV is used to measure the 3-D flow field and the turbulence intensity field around a round-ended pier.

After analyzing the measurement data recorded from 13:00 10~(th) March to 16:00 10~(th) March 2007,we have induced some strong northern wind characteristics relating the wind speed and direction,the turbulence intensity,the turbulence integral scale and the power spectrum,etc.

The relative intensity of turbulence and velocity pulsation in exity of cross flow fan were studied byusing hot-wire anemometer measurements.

The results show that the higher the turbulent intensity, the bigger the biodegradation rate andvelocity.

By the indoor flume model experiment,the changing law of vertical velocity distribution and turbulent intensity of submerged vegetation channel linings are discussed.

Based on the obtained experimental data,the distribution rules of turbulent intensity and Reynolds stress in up and downstream of the circular cylinder at various gap-ratios are discussed.
