  1. Planar laser induced fluorescence ( plif ) was used to study the spray / wall impinging in constant volume vessel. the experimental result show that when fuel spray impinging on the plane wall, wall jet was formed while fuel impinging on a plane wall with a bump, when the wall jet meet the bump, a secondary jet can be formed. some parameters affecting the secondary spray were studied, including bump height, the secondary impinging distance, impinging distance and injector parameters

    對傳統燃燒室和bump燃燒室內燃油空氣混合過程進行了對比研究,發現燃油撞壁以後在傳統燃燒室壁面形成壁面射流,這一層燃油濃度很高,很難與空氣混合,而在bump燃燒室內,壁面射流遇到bump后,會在空間形成二次射流,二次射流進一步能快速與空氣充分混合。
