Spatial amplitude growth rates, average wavelengths, frequencies, and wave propagation speeds were measured for liquid sheets with co-current air streams impinging on the two opposite interfaces. High-speed photography was used to obtain the spatial amplitude growth rates and wavelengths. Wave frequencies were measured by means of a laser beam attenuation technique. The effect of viscosity on the wave frequencies was investigated by injecting glycerine-water mixtures through the two-dimensional atomizer. The spatial wave amplitude growth rate was found to decrease with increase in liquid mass flow rate but increase with increase in air velocity. The average wavelengths decreased with increase in both liquid mass flow rate and air velocity. However, the dominant frequency increased with increase in liquid mass flow rate and air velocity. The frequency also increased with a decrease in viscosity.
