Abstract: In a high speed water tunnel, incipient and desinent cavitation are investigated on a series of hemispherical nosed teflon bodies. The results are compared with those measured previously on a series of stainless steel bodies. The experiments cover a wide range of flow velocities and air contents of water. Large differences, both in cavitation appearance and in desinence and inception values are found between the teflon and stainless steel bodies. While desinent cavitation on the stainless steel bodies was probably caused by stream nuclei, it is shown that cavitation on the teflon bodies is produced by surface nuclei.
