“…The motor rotational speed is controlled by a voltage regulator. The rotational speed of the atomizer is measured by two different methods: (i) Fastscan SA-X (Photron, Japan) and (ii) ACT-3X tachometer by Monarch Instruments coupled to a remote optical sensor [11] (Monarch Instruments, model ROS-5W, USA). Droplet velocity and droplet size are analyzed using IMAGEJ [12] discharge.…”

We report experimental and theoretical results on a ballistic energy-conversion method based on a rotary atomizer working with a droplet acceleration-deceleration cycle. In a rotary atomizer, liquid is fed onto the center of a rotating flat surface, where it spreads out under the action of the centrifugal force and creates "atomized" droplets at its edge. The advantage of using a rotary atomizer is that the centrifugal force exerted on the fluid on a smooth, large surface is not only a robust form of acceleration, as it avoids clogging, but also easily allows high throughput, and produces high electrical power. We successfully demonstrate an output power of 4.9 mW and a high voltage up to 3120 V. At present, the efficiency of the system is still low (0.14%). However, the conversion mechanism of the system is fully interpreted in this paper, permitting a conceptual understanding of system operation and providing a roadmap for system optimization. This observation will open up a road for building power-generation systems in the near future.
