RÉSUMÉ

The performance of impinging-jet atomizers for gelled fluids was examined. An injection system based on prefixing the mass flow rate of the atomized fluid was designed and built. Plain and gelled water were used as working fluids. Three types of impinging jet atomizers (doublet, triplet, and quadruplet) at two impinging angles were utilized. The results indicate a tendency of the droplet size to decrease with the mass flow rate growth. Gels were more difficult to atomize than Newtonian fluids. The triplet atomizer was found to be superior to the doublet and quadruplet atomizers. The lowest Sauter mean diameter values obtained were 8 μm for water and 10 μm for gel with the triplet injector.
