The influence of liquid film thickness on airblast atomization
Abstract
Two specially designed airblast atomizers were employed to analyze the influence of initial liquid film thickness on mean drop size distribution. In the first atomizer test, a thin film of uniform thickness was produced by injecting the liquid through a porous plate just upstream of the atomizing edge. In the second test, the fuel entered the airstream through a thin slot. Film thickness was measured by a needle contact device, and drop size was measured by established light scattering techniques. It was observed that high liquid viscosity and flow rate produce thicker films, while thinner films produce better atomization.
