Flow seeding with an air nebulizer

Flow seeding with an air nebulizer  In the framework of studies on anemometric measurements or tomographic visualizations, the seeding of a reactive flow by a nebulizer has been analyzed. In order to determine the performances of this apparatus, different liquids have been tested to evaluate the influence of their physical properties on the droplets size distribution. Measurements have been made using a Phase Doppler Anemometer. It is shown that the mean D 10 diameter lies between 2 and 3 μm, whatever the liquid may be, except pure water, and that, within a certain range, viscosity and surface tension have little influence on the size distribution. The ability of these liquids to seed reactive mixture is also discussed and especially their interaction in premixed flames. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

 In the framework of studies on anemometric measurements or tomographic visualizations, the seeding of a reactive flow by a nebulizer has been analyzed. In order to determine the performances of this apparatus, different liquids have been tested to evaluate the influence of their physical properties on the droplets size distribution. Measurements have been made using a Phase Doppler Anemometer. It is shown that the mean D 10 diameter lies between 2 and 3 μm, whatever the liquid may be, except pure water, and that, within a certain range, viscosity and surface tension have little influence on the size distribution. The ability of these liquids to seed reactive mixture is also discussed and especially their interaction in premixed flames.
