Guz’, A. N.; Basmat, A. S. On the interaction of unsteady waves with a rigid sphere in a compressible viscous fluid. (English. Russian original) Zbl 0685.76033 Sov. Phys., Dokl. 34, No. 6, 495-496 (1989); translation from Dokl. Akad. Nauk SSSR 306, No. 4, 813-816 (1989). We consider the unsteady interaction of a fixed, perfectly rigid sphere in a compressible viscous fluid with an unsteady plane compressible wave. The known results for the case of an acoustic medium are obtained as a limiting case of the linearized formulation of the problem considered here.
