Spanwise correlation measurements have been made for a stationary and a transversely vibrating cylinder placed near a wall and exposed to oscillatory flows. The correlation was calculated, based on pressure measurements on the surface of the cylinder. The carriage technique was used in the experiment, to simulate the oscillatory flow. The tests were conducted for three different values of Keulegan-Carpenter number, namely 6, 20 and 65, where the Re number was 3.4 × 104 for KC = 6 and 6.8 × 104 for KC = 20 and 65. The corresponding β number range was from 1,050 to 5,700, the lower end of the range corresponding to KC = 65. The tests were conducted for various values of the gap between the cylinder and the wall, normalized by the cylinder diameter, e/D, covering 0-2.3. The range of double-amplitude of cylinder vibrations, normalized by the cylinder diameter, 2A/D, was 0 - 0.7 in the tests. The results indicate that the correlation increases tremendously with the wall proximity, as far as the lift force on the cylinder is concerned. However, the effect of wall proximity appears to be insignificant, when fluctuations in surface pressure, either in the form of organized motion, namely the vortex shedding, in the case of wall-free cylinder or in the form of disorganized wake flow in the case of wall-mounted cylinder are considered. Regarding the influence of vibrations on the correlation, it was found that the correlation coefficient first increases with increasing amplitudes of vibrations. However, the increase in the correlation with increasing amplitudes was found not to be as large as in steady currents. The experiments indicate that the correlation coefficient begins to decrease with further increase of the amplitudes. It was found that this occurs for 2A/D larger than about 0.2 for KC = 6 and for 2A/D larger than 0.3 for KC = 20 and 65.
