  1. This dissertation is about theories and applications research of cfi, includes four main parts : first, the theoretical modeling of computational flow imaging corresponding to shadowgraph, schlieren, interferometric and planar laser induced fluorescence ( plif ) is developed

    本文對cfi的理論和應用進行了研究，主要包括以下四個方面： 1在總結國外cfi工作的基礎上，創新地建立了一套嚴格的、基本完善的、並具有較強針對性的計算光學流動顯示技術（ cfi ）的理論體系。
  2. Computational flow imaging ( cfi ) uses theoretical predictions of the interaction and transmission of optical waves through theoretical flowfield to generate digital pictures that simulate real observations. it was used to construct flow visualization corresponding to shadowgraph, schlieren, interferometric and planar laser induced fluorescence ( plif ) images. by providing a better insight into the flow physics and cfd code behavior, cfi is proving to be extremely useful to experimentally validate cfd codes

    計算光學流動顯示技術（ computationalflowimaging - cfi ）就是把數值計算（ cfd ）獲得的流場中的物理場，經過與實驗相同的計算光學（全息干涉、紋影、陰影、平面激光誘導熒光）的過程轉換為所需的各個方向與試驗流動顯示圖像相對應的計算流動圖像。
  3. The experimental investigations were first conducted on diesel spray wall - impingement mixing process with or without a bump on a flat wall and in a combustion chamber by means of plif method in the self - made constant volume combustion spray simulation set - up which can reproduce the typical working conditions and high - pressure fuel injection of modern diesel engines. the simulation computation of a cfd code about them was then carried out

    首先在自行研製的、可以模擬現代柴油機典型工作環境及高壓燃油噴射特性的定容燃燒噴霧模擬裝置上用片狀激光誘導熒光法（ plif ）對平壁上、燃燒室內不設置和設置bump的柴油噴霧撞壁混合過程進行了試驗研究，然後又用cfd多維數值分析軟體對其進行了模擬計算。
  4. Application of plif in research on supersonic combustion

    平面激光誘導熒光技術在超聲速燃燒中的應用
  5. Using plif - cage technique for treatment of degenerative instability of lower lumbar spine

    后入路椎體間融合籠治療退行性下腰椎不穩癥
  6. 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。
  7. Planar laser induced fluorescence ( plif ) and multi - dimensional cfd software was used to study the fuel - air mixing process in traditional combustion chamber and bump combustion chamber, the experimental and simulated result agree well in room condition. the fuel - air mixing process in high pressure and temperature in traditional and bump combustion chamber were compared. the result show that fuel and air can mix more quickly in bump combustion chamber than in traditional combustion chamber, fuel - air mixture in bump combustion chamber is more homogenous than in traditional chamber

    進一步對高溫高壓下傳統燃燒室和bump燃燒室內燃油空氣混合好壞進行了對比研究，提出了衡量燃油與空氣混合好壞的三個指標，發現bump燃燒室內燃油能在更大的體積內與空氣混合， bump燃燒室內燃油比傳統燃燒室內燃油分佈相對更均勻， bump燃燒室內燃油濃度耗散率為傳統燃燒室內燃油耗散率2 . 8倍，能更快與空氣混合。
