Aerodynamics of Lattices in an Unsteady Flow. Part 2,
Abstract
The unsteady flow of the gas through lattice has a series of special peculiarities which qualitatively differ the flow pattern of lattice in compressible flow from the corresponding picture in the incompressible fluid. The number of such special peculiarities at the subsonic rates of flow of gas includes the phenomenon of acoustic resonance. Gas in turbomachine as a result of compressibility has the capability to complete natural oscillations in the general case in three directions: radial, axial and circular. If one of the natural frequencies of oscillation of gas coincides with the oscillation frequency of blades, then the forced oscillations of gas can arrive at resonance.
