Particle Tracking Velocimetry (PTV) Algorithm for Non-uniform and Non-spherical Particles

Abstract

An algorithm for velocimetry working with the individual identification of seeding particles in a flow is developed in this paper. The algorithm is able to find particle pairs by the intensity of the light scattered and the size and shape of the particles. The velocity field of fluids and sediment particles of irregular size and shape and higher density than the fluid were experimentally measured An experimental flume and a particle tracking velocimetry (PTV) system provided with a double pulsed laser and high speed CCD camera was used For image analysis an algorithm presented in this work was able to give sediment velocities for different particle ranges and proved to be a useful and efficient tool for PTV analysis of flows seed with non-spherical and non-uniform tracers
