黏性液体三次雾化的试验研究
Experimental Research on Tertiary Atomization of Viscous Liquid
摘要
Abstract
Experimental research on supersonic secondary atomization of viscous liquid and tertiary atomization of viscous liquid were carried out based on impinging-stream technology. Influence factors of tertiary atomization were analyzed. The results show that oil mist particle diameter decreases with the increase of intake pressure and compressed air flow; oil mist concentration decreases gradual- ly with the increase of intake pressure; change rate of particle diameter decreases with the increase of Weber number. When Weber number is less than 5. 376 ,change rate of particle diameter is larger than zero;when Weber number is more than 5. 376, change rate of particle diameter is less than zero; when Weber number is at 22.81, maximum absolute value of change rate of particle diameter occurs and throat diameter of nozzle is the main influence factor of change rate value of particle diameter.关键词
