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。

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、并具有較強針對性的計算光學流動顯示技術( cfi )的理論體系。

And the paper analyzes the physical reasons that the supersonic flow of fadw degrades the optical quality . and the structure of free - vortex jet of fadw is studied using the methods of shadowgraph and lsi , respectively 并利用陰影法和剪切干涉法對該窗口的射流流場結構進行了實驗觀察和測量,對其所涉及的氣動光學現象進行了相應的實驗測量和分析。
