Abstract

The performance of ejector-Venturi scrubbers has been studied experimentally. Data have been obtained on overall pressure drop, axial pressure profiles and droplet sizes. The effect of throat diameter, length and spray angle was investigated. Empirical models for pressure drop across Venturis have been tested against the data. Only when the model is tuned to the experimental data they are successful. The model of Azzopardi et al. which incorporates all the important physical mechanisms, has been successfully adapted to handle ejector-Venturi. It has been found to give accurate predictions. © 2002 Elsevier Science Ltd. All rights reserved.
