Development of phase doppler anemometry method with a measurement object in the form of a cylinder

Abstract

Developing methods for diagnosing particle sizes in an aerodynamic flow is a pressing issue in a number of technical applications such as engine building, power engineering, coating, and others. One of the methods for diagnosing particle sizes is the phase Doppler anemometry (PDA) method. It is a laser optical method for simultaneously measuring the speed and size of spherical particles. The purpose of this work is to test the performance of a method that implements phase Doppler anemometry to obtain the dependence of the phase shift on photodetectors on the diameters of the wires. The work presents a differential optical scheme of the installation with a helium-neon laser as a radiation source.
