The driving force behind this work was to develop a robust piezo electric droplet generator for spray drying applications. This report is a comprehensive account of the basic theory underlying droplet generation and the suitability of piezo technology for droplet generation. It begins with a theoretical description of the droplet generation principle and ends with an insight into the future developments.
The present work deals wit the fabrication of a robust Piezo electric droplet generator utilising the basic renowed phenomena of forced jet disintegration and using the Rayleigh criteria for jets. A careful insight into the basics of droplet generators and ink jet printers proved to be of enormous help in designing the current model.
