Abstract

Within the framework of a model of a twisted flow of an inviscid incompressible liquid, we solve the problem of determining the frequency and amplitude of oscillations caused by the precession of a helical vortex core in the suction tube of a hydroturbine from the specified integral characteristics: vortex intensity, liquid flow rate, and momentum and moment of momentum fluxes.
