The microfluidic Kelvin water dropper

Pressure-driven ballistic Kelvin's water dropper for energy harvesting.

In this paper, we introduce a microfluidic-based self-excited energy conversion system inspired by Kelvin's water dropper but driven by inertia instead of gravity. Two micro water jets are produced by forcing water through two micropores by overpressure. The jets break up into microdroplets which are inductively charged by electrostatic gates. The droplets land on metal targets which are gradua...

Waste water ammonia stripping intensification using microfluidic system

This paper reports the results of experimentally removing ammonia from synthetically prepared ammonia solution using a micro scale mixing loop air stripper. Effects of various operational parameters (such as: pH, air flow rate, wastewater flow rate and initial ammonia concentration) were evaluated. By increasing the pH from 10 to 12.25 the amount of KLa increased from 0.26 to 0.73 hr-1. A consi...

A discussion on Neumann-Kelvin model for progressive water waves

This paper focus on the role of the capillary in the modelling and the analysis of progressive waves at the surface of the sea. It is proved that the classical Neumann-Kelvin model is fully instable and should be modified in order to be mechanically reliable. It is shown that the easiest way to take the capillary into account is to use a formulation where the normal displacement of the free sur...
