The results of model and in situ measurements of the fluctuating wind pressures over a cooling tower are presented. On the model, wind pressures were detected by means of two Brüel-Kjaer microphones at Re = 5.04 × 105; the pressure transducers used in situ were identical to those used in measurements on the Post Office Tower, London (Gt. Britain), at Re = 3.48-5.22 × 107. The power spectral densities obtained from the model and in situ measurements are in good agreement. Great attention was given to the decay of the coherence function above a certain reduced frequency the value of coherence ceases to diminish. Values of normalised spectral densities and coherence functions are recommended for theoretical calculations of the dynamic response of a cooling tower.
