摘要：

A diagnostic technique based on the oxygen quenching of laser-induced fluorescence from naphthalene has been developed to investigate whether internal circulation is important in submillimeter hydrocarbon droplets. Images have been obtained in 300-500 pm diam droplets of decane. Oxygen is absorbed into the surface liquid of initially oxygen-free droplets and quenches the naphthalene fluorescence. The resulting fluorescence image, including darker zones where oxygen is present, is recorded on a 2-D CCD detector. Computer processing of the images obtained with and without oxygen present reveals internal circulation patterns. © 1990 Optical Society of America.
