Popis: A model of numerical experiment involving the use of the modernized method of discrete vortices is proposed for fully simulating the main mechanisms through which vibrations of tube bundles are excited: periodic vortex separation and fluidelastic excitation. A mathematical model simulating fluidelastic excitation of tube bundle vibrations by an external cross flow and intended for calculating the stability curve for a concrete row of tubes is developed on the basis of available experimental data.
