Breakup of Volatile Liquid Jet in Hot Cross Flow

摘要: Abstract Liquid jet in cross flow has been a widely studied subject although most of the experimental work carried out at ambient conditions. The present study involves investigation behavior an ethanol injected into flowing air elevated temperatures up to 428 K. Spray parameters such as trajectory and drop size distributions are measured compared for cold hot Experiments conducted range liquid-to-air momentum ratios ( Q ) ∼ 4 – 13 Aerodynamic Weber numbers We 15. Though existing literature attributes effect temperature on effective change due density variation, shows interesting observations where results vary spite maintaining similar magnitudes between It is observed that higher consistently manifested by found temperatures. proposed physical parameter,density ratio, needs be considered additional parameter account these differences. Therefore, new correlation which match data different measurements indicate considerable amount evaporation fine droplets formed leeward portion resultant spray flow.
