An online PIV system as applied to the study on hollow swirling liquid spray

摘要

In this paper a newly developed online PIV system was introduced. It was firstly teste din measurement of swirling water velocity distribution in a water cup, and then was used to study hollow swirling liquid spray from a pressurized swirling atomizer, Two-dimensioal velocity distribution of the moving droplet in the spray flow field was obtained and analyzed.
