OSCILLATIONS OF A ROTARY FLUID FLOWING OUT OF A CLOSED VESSEL
V. V. Orlov and A. N. Temnov UDC 532.5 Consideration is given to the problem of the proper motion of a rotary fluid that fills the entire cylindrical tank in the presence of outflow through a rigid bottom. The problem is solved in a quasistatio-nary formulation within the framework of the ideal-fluid model with allowance for hydraulic losses in the flow of the fluid through the bottom of the vessel. The spectrum of eigenvalues is investigated and the characteristics of wave motions of the fluid are revealed; the results of calculating the wave numbers and the complex attenuation factor are given.
