Effervescent Atomizers with Enhanced Spray Characteristics

Popis výsledku v původním jazyce

Effervescent atomizer belongs to twin fluid atomizers and is characterised by relatively simple construction. It produces fine spray even at low pressure and with low amount of atomising gas. Regardless of it there is still potential to improve their atomization characteristics such as too narrow spray cone angle of the single hole atomizer in combustion applications and a presence of large droplets in the spray border which worsen exhaust gas emissions. In this work we studied a single-hole effervescent atomizer spraying light heating oil with air as an atomising medium in the "outside-in" gas injection configuration. We focused on modification of geometry of the atomizer exit section. Two atomizers, one with moderate, and one with intense helical swirler in front of the exit orifice were designed to expand the spray cone angle by a swirl of the gas-liquid mixture. Performance of the atomizer modifications were compared with plain orifice atomizer. An experimental study of atomization
