| Abstract(J) | 吸気管噴射燃料噴霧について，無次元数を用いた噴流形態の分類およびシャドウグラフ撮影による液膜分裂過程の可視化を行なった．吸気管噴射条件の燃料噴霧は液膜を形成し，液滴への分裂は軸方向に分布を持って発生することが明らかとなった．また，液滴からさらに微小な液滴への分裂は観測されなかった． Translation |
| Abstract(E) | This paper reports the atomization process of fuel spray in gasoline intake port injection. The classification of the jet configuration using dimensionless numbers in fluid dynamics was estimated that the fuel spray in the port fuel injection condition is in the wavy region. A shadow graph photography was used to visualize the liquid sheet breakup process. It was confirmed that the fuel injected from the nozzle formed a liquid sheet. For the subsequent breakup, it was found that the liquid sheet broke up into droplets with a distribution along the axial distance of the nozzle, and the secondary breakup, in which the droplets broke up into smaller droplets, rarely occurred. |
