“…This model has been selected instead of more complicated one-dimensional models (Weber 1931;Green 1976;Entov & Yarin 1984) because, in spite of its relative simplicity, the results obtained are in agreement with experimental evidence, both in the case of single capillary jets (Pimbley & Lee 1977) and in the case of slender liquid bridges (Sanz 1983;Mcseguer & Sanz 1985). Amongst the different types of instability appearing in a compound jet (Hertz & Hermanrud 1983) we analyse capillary instability only, which is the most interesting in ink-jet printing applications in order to predict the size of the resulting drops after the jet breakup.…”

The stability of an infinitely long compound liquid column is analysed by using a one-dimensional inviscid slice model. Results obtained from this one-dimensional linear analysis are applicable to the study of compound capillary jets, which are used in the ink-jet printing technique. Stability limits and the breaking regimes of such fluid configurations are established, and, whenever possible, theoretical results are compared with experimental ones.

“…It is also important that none of the forces or parameters change with Figure 3 is a plot of data collected by researchers at IBM and indicates the frequency-amplitude window in which satellites are created. 4 At amplitudes above the window, the satellites will forward-merge within a few wavelengths; at those below the window, the satellites backward-merge in the same range. The diameter of a satellite droplet is generally about one tenth the diameter of a primary droplet.…”

“…This requires a very expensive computer effort, which prohibits practical simulations. Lee (1974) and later Pimbley & Lee (1977) developed a nonlinear-direct-simulation technique that proved to be a simple and practical approach to investigate the nonlinear instability of a liquid jet. Tropey (1989) and Schulkes (1993) utilized variations of Lee's numerical-simulation methodology in their analyses of the instability of inviscid liquid jets.…”

The instability and subsequent atomization of a viscous liquid jet emanated into a high-pressure gaseous surrounding is studied both computationally and experimentally. Liquid water issued into nitrogen gas at elevated pressures is used to simulate the flow conditions in a coaxial shear injector element relevant to liquid propellant rocket engines. The theoretical analysis is based on a simplified mathematical formulation of the continuity and momentum equations in their conservative form. Numerical solutions of the governing equations subject to appropriate initial and boundary conditions are obtained via a robust finite difference scheme. The computations yield real-time evolution and subsequent breakup characteristics of the liquid jet. The experimental investigation utilizes a digital imaging technique to measure resultant drop sizes. Data were collected for liquid Reynolds number between 2,500 and 25,000, aerodynamic Weber number range of 50-500 and ambient gas pressures from 150 to 1200 psia. Comparison of the model predictions and experimental data for drop sizes at gas pressures of 150 and 300 psia reveal satisfactory agreement particularly for lower values of investigated Weber number. The present model is intended as a component of a practical tool to facilitate design and optimization of coaxial shear atomizers.
