In: 11th International conference on indoor air quality and climate paper, Copenhagen, Denmark; 2009. Glover A.R., Skippon S.M., Boyle R.D. Interferometric laser imaging for droplet sizing: a method for droplet-size measurement in sparse spray systems. WebThe method of droplet formation is based on disintegration, by gas jets, of thin liquid films formed as bubbles on a liquid surface. Using compressed air and CO2, we atomized gasoline (95 RON), diesel, and 0.1-2 wt.% aqueous solutions of sodium alginate with dynamic viscosities up to 210 mPa·s as a model of a highly viscous fuel.
