Coefficients for Calculating Radiation Impedances and Far-Field Pressures of Free-Flooded Ring Transducers
Abstract
Tables of coefficients for determining the radiation impedance and far-field pressure of a free-flooded vibrating ring in an arbitrary medium at 45 frequencies for each of 36 ring geometries were produced. The only restriction on the known velocity distribution for using the tables is that the inside, top and bottom, and outside normal surface velocities must be uniform. Simple formulas for determining the normal surface velocity distribution for some special cases and formulas for determining the radiation resistance and far- field pressure in the low-frequency limit were developed.
