Orifice damping effect is the key point in study of fluctuating internal pressure and wind-induced dynamic responses of roof structures with opening in turbulence flow.

A new method for identifing aerodynamic derivatives of bridge decks in turbulence flow is put forward in this paper.

This paper reports the measurement of transition location change of NLF(2)-0415 swept wing in a low-speed flow along with the attack angle based on sublimation method in a low turbulence wind tunnel mounted at Northwestern Polytechnical University.

Based on the data of a turbofan engine inlet total pressure distortion experiment, the methods to predict inlet dynamic pressure turbulence were studied.

In order to study the effect of plasma assisted combustion,the combustion products of methane-air mixture and trend of turbulence at exit of combustor were investigated by numerical simulation and analyses.

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.
