This thesis contains measurements of the wall pressure fluctuations on cylinders in a bundle in turbulent axial flow in a cylindrical channel. The measurements were made for the purposes of obtaining insight into the nature of the turbulent pressure field and providing analytical approximations of wall pressure correlations required by a previously derived theory for predicting the flow-induced vibration of cylinders in axial flow. / The turbulent pressure field at the walls of the cylinders is examined in both the frequency and time domains via measured power-spectral densities, cross-spectral densities, auto-correlations and cross-correlations in azimuthal and longitudinal planes in the cylinder bundle over a range of flow velocities. The data is then nondimensionalized to give dimensionless power-spectral densities and azimuthal (or lateral) and longitudinal correlation functions, which are then approximated analytically and compared to a previous analytical approximation for pipe flow. Typical force-per-unit-length spectra are also obtained from the pressure measurements.
