Notizen: A multiorifice spray generator with two different modes of operation is developed. The impulse jet operation mode covers a wide range of droplet frequencies and produces arrays of droplets with controllable spacing, but with a wide size spectrum. This ejector also operates in pressurized flow mode. In this mode, optimum disturbance frequency breaks up the liquid jets into uniform size droplets, resulting in a monosized spray. Precise control of fuel flow rate and droplet size is achieved.

Notizen: The physical phenomena associated with two-phase annular-mist flow in vertical pipes are considered. A new mechanistic model is developed to predict liquid entrainment, liquid film thickness, in situ velocities, and pressure drop. The model is compared to field data and found to be superior to the three commonly used empirical correlations.
