Liquid Jet Disintegration and Spray Characteristics in Subsonic Air Streams.

Analysis of Disintegration of Planar Liquid Sheet Sandwiched between Gas Streams with Unequal Velocities and Resulting Spray Formation

A temporal stability analysis was carried out for a planar liquid sheet sandwiched between two gas streams moving with unequal velocities. Perturbation analysis was carried out up to second order using the initial amplitude of disturbance of the liquid sheet as the perturbation parameter. Both para-sinuous and para-varicose modes were investigated to determine the dominant break-up mechanism. T...

Response of Spray Formed by Liquid Jet Injected into Oscillating Air Crossflow

Experimental results on the characteristics of near-field (up to x/D=8) spray formed by a liquid jet injected into an oscillating air crossflow are presented. The modulation frequency is varied from 90 Hz to 450 Hz and the crossflow velocity (25-100 m/sec) and ambient pressure (2-3 atm) are systematically changed to investigate the spray response to modulated crossflow velocity over a range of ...

Stability of Subsonic Jet Flows

An overview of recent experimental results on instability and dynamics of jets at low Reynolds numbers is given. Round and plane, macro and micro jets are under the consideration. Basic features of their evolution affected by initial conditions at the nuzzle outlet and environmental perturbations are demonstrated.
