Abstract

Precise, controllable ultrasonic spraying nozzle can reduce waste and lessen environmental impact, compared with ordinary pressure spray nozzles. Concerns over the environment and unacceptable quantities of waste have caused scientists, engineers and designers to adopt ultrasonic spraying systems as a technology that is more precise, more controllable and more environmentally friendly. They are replacing pressure nozzles in a wide range of industrial and R&D applications with their characteristic soft spray. They also open up a broad range of new application possibilities, for substrate coatings, moisturizing, spray drying, web coating, fine-line spraying, and many other industrial and R&D applications. They are ideal, for example, when extremely low flow rates are required. That’s why they are also introduced into our studies of supercritical fluid particle formations.
