Novel modifications of Effervescent Atomizer, Performance, Advantages and Drawbacks
Popis výsledku v původním jazyce
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 a plain-orifice atomizer. An experimental study of atomization process was made on cold test bench. Swirling the mixture led to a significant increase of the spray cone angle at low gas to liquid ratio by mass (GLR). An increase of the gas mass fraction in the mixture inhibits theswirl action on the spray cone expansion. The swirl effect diminishes with GLR rising above 15 %. Another two atomizers were designed with aim to reduce droplet size on the spray edge: an atomizer with secondary air at the exit orifice a
