A critical review of two-phase gas-liquid industrial spray systems

Droplet size distribution measurement of a two-phase, two-component spray is an intricate process. This type of spray is three-dimensional in nature; therefore multi-dimensional flow field measurement of the spray is indispensable. Particle Dynamic Analyzer has been used for spray characteristic measurements issuing from a wide variety of nozzles. However, a reliable method for the calibration of the droplet size and velocity measurements is required to ensure an unbiased measurement. The application of the is still a challenge in highly concentrated multiphase spray. In this paper, a detailed review of the advanced experimental techniques and basic theory of two-phase, two-component sprays is discussed. Special emphasis has been given to the Particle Dynamic Analyzer systems and digital image analysis measurement techniques. There are several studies found in the literature, which explain the fundamental characteristics of turbulent jets and sprays. However, limited studies can be found related to two-phase, two-component horizontal flow sprays. 2009 Praise Worthy Prize S.r.l. - All rights reserved.
