Summary
After a survey of previous work on the wake and sound fields of a cylinder moving through air, a description is given of apparatus designed to record the fluctuations of velocity (recorded by hot-wire) in the wake of a cylinder towed through water and the fluctuations of pressure in its vicinity (recorded by probe hydrophone). The results show that the two types of measurement are correlated and consistent with the field of a dipole source. The Strouhal number as measured is consistent with a forced vibration of the cylinder over quite a range of speed. Attention is drawn to some possible applications of the results.
