Pressure-swirl atomiser modelling T.L. Chan & W.T.V. Leung" Department of Mechanical and Marine Engineering, Faculty of Engineering, Hong Kong Polytechnic, Hong Kong * Graduated student ABSTRACT The pressure-swirl atomiser, probably is one of the most widely used atomisation devices, having applications in broad areas of industrial, chemical, and agricultural engineering. Hence, successful simulation will be valuable in terms of time and cost-effectiveness for experimental work and will also simplify the atomiser design process. The Ballistic Modelling (BM)TDiscrete Droplet Modelling (DDM) method has been employed for modelling a pressure-swirl atomiser (Dyna-Coin nozzle) with solid spray cone. The characteristic of its liquid spray is of considerable importance to the operation and performance of combustion systems. A two- dimensional spray model has been developed to simulate a continuous spray under steady-state condition. This computer model can simulate the re
