Prediction of Discharge Coefficient of Internally-Mixed Twin-Fluid Atomizers
Original language description
Flow rate of atomized liquid is one of the nozzle design parameters. Several research works have proposed cor-relations for prediction of the discharge coefficient of twin-fluid atomizers with internal mixing. We have used linear combination of two known physical models for two-phase discharge; the Homogeneous Flow Model and Separated Flow Model which correspond to the extreme cases of gas-liquid discharge without slip and discharge with maximum slip respectively. Corrections to include effects of fluid physical properties and nozzle geometry to the discharge were added and resulting model has been compared with experimental data for a set of single-hole effervescent atomizers under wide range of inlet gauge pressures and gas to liquid mass flow ratios. Good match with correlation coefficient R2 = 0.95 was found between the model based and the experimentally found discharge coefficients. A free-access web application was compiled to serve as a design tool for engineers.
