| Abstract: | Wind tunnel simulation was done for buildings such as cooling tower as well as the surroundings using Reynolds number from standard criteria as the driving force of similar criteria.Scale model of 1∶1,500 was used in the wind tunnel test to study the impact of cooling tower and other surrounding buildings as well as mountains of Taohuajiang Nuclear Power Plant site on the near-field flow and radionuclide migration and diffusion for the purpose to obtaining atmospheric dispersion characteristics of near-field site.Experimental results showed that the existence of mountains or buildings would arouse distortion of aerodynamic flow field,over the mountains the speed of measuring points and turbulent intensity distribution profiles were complex. |
