In this paper, according to the real distribution of wind-force, a problem of equivalent across wind-force on tall columns is discussed Compare with the Code, the modification value is obtained based on the theory of potential equivalent, the equivalent diametre of the cone is given.

The non-uniformity of transversal air distribution in a chain grate stoker can seriously affect the stoker efficiency.

Analysis of flow characteristics around train-bridge system under cross wind and train induced wind;

The influence of cross wind on the air flow field in a natural draft dry cooling tower is studied experimentally on the basis of similarity rules.

Three-dimensional flow will be appeared near the front and rear of the high-speed train when it is running on the bridge under the cross wind and train induced wind, also the flowfield near the middle part of the train will be affected at some degree.
