Abstract.

An inexpensive device for generating fogs of micron-sized droplets is described. The liquid does not pass through small orifices. It is easily constructed and suitable for liquids containing particulates, seeding high-pressure environments and laser Doppler anemometry, and particle imaging velocimetry. Phase Doppler anemometry measurements show size distributions as a function of pressure for three working fluids. The device consistently produced a narrow size range with a mean diameter of a few microns.
