The aim of this ZIM-funded project (ZF40329l8JA7), carried out in collaboration with Athena Technologie Beratung GmbH, was to develop an intelligent, modular, ultrasound-based dispersion system for liquids with different properties. A key challenge of the project was to disperse liquids whose properties can vary significantly. Viscosity was identified as a key factor influencing atomisation capability.

To atomise highly viscous liquids, an ultrasonic standing wave system was developed, which, for the first time, enabled the atomisation of liquids with a viscosity of up to 96,000 mPas (e.g. viscous adhesive).

To atomise minute quantities of low-viscosity liquids with a defined droplet size of 8 µm, a miniature capillary wave atomiser with an operating frequency of 257 kHz was constructed and integrated with a precision pump to form a fully operational atomisation system.

To atomise small quantities of low-viscosity liquids, the vibrating-mesh atomiser technology was adapted and developed as a module. The ultrasonic systems are operated using the newly developed, versatile ATHENA ultrasonic generator.
