The paper describes a method for tracking the jets of gas flows based on the Lagrangian-Eulerian approach usage. A system of integral equations describing q3d- flow of gas in a curvilinear coordinate system associated with the surface of the turbomachine rotation is presented, as well as a system of integral equations describing an axisymmetric swirling flow in a cylindrical coordinate system. Using the method for tracking jets of gas flows, a possibility to research a variety of unsteady processes is shown. The following phenomena are studied: the segregation phenomenon of hot and cold jets of gas on the turbine rotor blades surfaces, clocking-effect of aerodynamic interaction in the 1.5 turbine stage, determining the trajectory characteristics of unsteady gas flow in the turbine, axisymmetric swirling flow of gas in the system "engine-nacelle-external flow".
