New concept: Low-pressure, wide-angle atomiser
Paper summarises results obtained in feasibility study of a novel pneumatic atomiser for generation of a spray of fine droplets. The new feature is pulsation of supplied air so that it issues in anti-phase from two nozzles acting on the water jet. The pulsation is generated using an integral no-moving-part fluidic oscillator. Tests involved recording by high-speed camera and laser-light scattering measurements of droplet size. Despite the low pressure (<10 kPa) of supplied air, the mean diameter of droplets was small - mere 158 mu m - and the spray fan angle full 90 deg. (C) 2014 Elsevier B.V. All rights reserved.
