| Abstract: | The problem of spherical sound-wave diffraction by a sphere in a viscous medium is discussed. Applying the method of separation of variables, we obtained exact formulas for the hydrodynamic field elements in a low-viscosity medium. Furthermore, by applying the Morse 1, 2] and Watson 3] method to the exact formulas, we determined asymptotic formulas for the same quantities in the case of long and shortwave propagation.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 133–146, January–February, 1973. |
