摘要
采用高速摄影仪以及Matlab软件对生物油雾化特性进行实验研究,考察蠕动泵转速和生物油温度对雾化角度和液滴索特平均直径(SMD)的影响,并研究喷射距离对液滴SMD的影响。研究结果表明:当生物油温度为35℃时,随着蠕动泵转速的增大,雾化角度先增大后减小,其最大值为47.10°;而生物油温度对于雾化角度的影响较小。液滴SMD随着喷射距离的增加先增大后减小再缓慢增大。在生物油温度为35℃、蠕动泵转速为300 r/min的条件下雾化液滴的冷凝效果最好。
The spray characteristics of bio-oil were investigated by high-speed camera and Matlab. The effect of the peristaltic pump rotation speed and bio-oil temperature on atomization angle and Sauter mean diameter （SMD）was investigated. Moreover, the effect of jet distance on SMD was also studied. The results show that the atomization angle increases at the beginning, and then decreases with the increase of the rotational speed, and the maximum is 47.10° when the bio-oil temperature is 35 ℃. But the effect of bio-oil temperature on the atomization angle is little. With the increase of jet distance, the droplet SMD increases firstly, then decreases, and increases again slowly. The condensation effect of atomized droplets is the best at oil temperature of 35 ℃, peristaltic pump rotation speed of 300 r/min.
