Visualization of Flows in Turbomachinery.

Abstract

A method of gas visualization based on laser induced fluorescence has been theoretically and experimentally investigated. Liquid droplets seeded with fluorescent substance were introduced locally in an air flow. A laser light sheet is used to scan the flow field. The light emitted by fluorescent substance is used to obtain, after filtering the image of a point on specific streamline. The method has been applied to the visualization of streamlines around a cylinder. The possibility of the use of this method in the visualization of flows in turbomachines has been investigated. Some of the main features of the necessary equipment have been defined too.
