| Abstract: | By Making use of wind tunnel method, this paper presents a study of dispersion for cylindric wind tower, whose height is about 70m and diameter of Cross section 29.7m. Experiment results show that wake region behind wind tower can cause velocity deficit, turbulence excess and downwash phenomenon. The cross-wind and perpendicular direction concentration distributions behind wind tower maintain basically Gaussion form, but central line of plume significantly slents to ground when mean wind velocity of source height is large than 2.6m/s. Further more, tilted model of Gaussian plume and parameter system have been recommended to predict concentration distribution behind wind tower. Performance tests have shown that its accuracy is good. |
