Web1 de ago. de 2012 · Abstract. Instability of a liquid jet issuing from an elliptic nozzle in Rayleigh mode is investigated and its behavior is compared with a circular jet. Mathematical solution of viscous free ... Web1 de jan. de 2004 · A low-density gas jet injected into a high-density ambient gas is known to exhibit self-excited global oscillations accompanied by large vortical structures interacting with the flow field. The primary objective of the proposed research is to study buoyancy effects on the origin and nature of the flow instability and structure in the near-field of …

WebThe jet forms near a rotating disk, goes to the inte rface near the sidewall, and converges to the axis near the interface. New circulatory cells emerge in both fluids and the interface significantly bends. The instability develops after such flow pattern becomes well formed. The instability focuses near the interface where the jet-like Web6 de mar. de 2024 · Abstract. The appearance of instability modes on subsonic and supersonic impinging jets is a phenomenon of great interest that has been observed in jets produced by nozzles of different sizes. The present study describes these instabilities in millimeter-sized supersonic jets produced by convergent and convergent–divergent … simplicity 8659

Web1 de jan. de 2000 · Abstract. A linear instability analysis is performed to arrive at the dispersion relation that governs the instability of an inviscid liquid jet emanated into an inviscid gas. The velocity profile within the jet is varied from parabolic to uniform in order to model the effects of its relaxation on jet instability and intact length.
