A WIND-TUNNEL STUDY OF WIND LOADING ON COOLING TOWERS OF SHA-LIN-ZI POWER STATION
沙岭子电厂冷却塔群风荷载的风洞研究

In this paper the results of wind tunnel testing of fluctuating as well asmean pressures on models of four neighboring cooling towers of Sha-Lin-Zi Power Station, arranged nearly in line under directions of prevailing wind and of peak speed are presented and discussed. It shows that, the peak suction (mean pressure) of certain towers, due to proximity interference, will be moderately greater, and the fluctuating pressure (rms value) of downstream towers, due to wake interference, may be several times larger than that of isolated tower respectively. Meanwhile the frequency of the peak value of pressure spectra will be two times higher.
