Investigation of the Atomization Behavior of a Doublet Like-on-Like Impinging Jet Atomizer in a Wide Range of Reynolds and Weber Numbers

The spray characteristics of a doublet like-on-like impinging jet injector in dependence upon Reynolds and Weber numbers have been investigated under ambient pressure and temperature conditions. The breakup behavior has been visualized with the shadowgraph technique. Various fluids have been used to cover a wide range of Reynolds and Weber numbers, i.e. about 60≤Re≤30,000 and 100≤We≤30,000. Different atomization regimes could be observed at different Re and We conditions.
