A method to determine liquid concentration in non-stationary axisymmetric sprays

A method to determine liquid concentration in non-stationary axisymmetric sprays  A method to determine liquid concentration in non-stationary axisymmetric sprays of high density and velocity is described in this paper. In this method a Phase Doppler Anemometer (PDA) is used together with a light extinction technique based on a CCD camera. Image acquisitions and PDA measurements are taken at the same time from injection start during a very short temporal window. The data obtained with both techniques are processed independently and then combined to obtain the local liquid concentration and number of droplets per unit volume. In addition, the volumetric flux of liquid can be calculated because the droplet velocities are known. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

 A method to determine liquid concentration in non-stationary axisymmetric sprays of high density and velocity is described in this paper. In this method a Phase Doppler Anemometer (PDA) is used together with a light extinction technique based on a CCD camera. Image acquisitions and PDA measurements are taken at the same time from injection start during a very short temporal window. The data obtained with both techniques are processed independently and then combined to obtain the local liquid concentration and number of droplets per unit volume. In addition, the volumetric flux of liquid can be calculated because the droplet velocities are known.
