ディーゼル燃料噴射ノズル噴孔近傍における超高密度液滴の分裂に関する研究 Study of Droplet Breakup of Diesel Fuel Spray near Nozzle Exit ディーゼル ネンリョウ フンシャ ノズル フンコウ キンボウ ニオケル チョウ コウミツド エキテキ ノ ブンレツ ニ カンスル ケンキュウ 駒田, 佳介 Diesel Engine Fuel Spray Droplet Size Velocity Spray Width Diesel Engine Fuel Spray Droplet Size Velocity Spray Width application/pdf 論文(Article) A laser 2-focus velocimeter (L2F) was used for measurements of velocity and size of droplets inside diesel sprays intermittently injected into the atmosphere by using 8-hole injector nozzle. The diameter of the nozzle orifice was 0.125mm. The rail pressure was set at 60 MPa, and the injection quantity was set at 4mm3/injection. Measurement plane was located at 10 mm downstream from the nozzle exit. The spray image was taken by the high-speed camera, and the spray width was evaluated by using spray image. The spray width was large at the early period of injection duration. The size of droplets was small at the time when the spray width was large. It became clear that there was a negative correlation between the spray width and the size of droplets. 福岡工業大学総合研究機構 2020-12-25 jpn departmental bulletin paper VoR http://hdl.handle.net/11478/00001581 https://fit.repo.nii.ac.jp/records/614 24345725 福岡工業大学総合研究機構研究所所報 3 7 10 https://fit.repo.nii.ac.jp/record/614/files/福工大-総合研究機構-所報3(駒田佳介).pdf application/pdf 554.3 kB
