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 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.

The instability of a circular cylindrical jet of liquid in air is studied on the assumption that the wavenumber k of the disturbance is complex while its … Web9 de nov. de 2024 · The primary atomization deteriorates as the load decreases, especially under low loads. 4. The effect of the liquid sheet thickness on the instability is nonmonotonic. When the thickness is greater than the thickness at h =0.3, the liquid behaves like a full liquid jet, and the instability is independent of thickness.
Web1 de jun. de 1994 · Abstract. A novel dispersion equation describing the instability of low velocity, liquid jets is derived using an integro-differential approach. The explicit form of the derived equation enables much easier prediction of the most unstable wavenumber and disturbance growth rate than does Tomotika's implicit, complex dispersion relationship. 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 …

In this paper we examine, in the linear approximation, the stability of a compound jet of nonmiscible liquids with respect to small axisynmetric perturbations of the interfaces. The instability characteristics are given for jets with inviscid and very viscous outer ...
