Abstract: 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...
