Three-dimensional disturbances are considered and a … Web14 de abr. de 2024 · In order to characterize the bending jet, we track the evolution of a jet trajectory at the onset of a bending jet. At an early stage, small perturbation amplifies with time in space such that the first jet bend occurs at the jet end. The initial waves propagate at the growth rates of ki ∼ −10 2 m −1 and ωi ∼ 10 Hz.
