intake duct
解釋
進氣裝置-
So the flow field visualization in intake duct was realized. according to the experimental requirements, tow different transparent intake duct model were designed. a real - time holographic interferometry measuring system was developed, in which he - ne laser was used as light source, and a ccd ( charge coupled device ) video camera was used to grab the interferogram. a intake simulation system was build - up
本文根據研究要求，用甲基丙烯酸甲酯製作了兩種不同類型的進氣道透明模型；設計並建立了利用he - ne激光器做光源的實時全息干涉測量光學系統；設計了一套能夠模擬進氣道在某一氣門升程時的進氣系統，用mtv - 1802cbccd攝像機對干涉條紋進行了實時採集。 -
A useful technique has been provided and developed for the researching and analyzing the factors and variation of flow field in the intake duct of diesel engine. to find out a new method to measure flow measurement, different intake duct on different conditions are experimented and researched by real - time holographic interferometry. real - time holography interferometry has many characteristics, such as high precision, non - destructive, high contrast of interference fringes and full field test
該方法具有精度高、非接觸、條紋對比度好、對被測物體形狀和表面無特殊要求的特點，實驗了對三維非定常流動過程的可視化實時採集，為了解和分析不同流量、不同結構參數下進氣道內氣流運動狀態和流動特性的變化關系及其影響因素提供了一種有效的測試手段。 -
Flow motion in intake duct of diesel engine is an important factor, which, affects the process of combustion and mixture of diesel engine
內燃機進氣道內氣體的流動對混合氣的形成、燃燒和排放有著重要的影響。 -
A good foundation is provided for further investigating the changing flow fields of intake duct and confirming the numerical simulation of computer three - dimensional unsteady flow
本文的研究結果可為內燃機進氣道的研究和改進提供基礎的資料，並為驗證內燃機氣道數值模擬計算提供準確的、科學的實驗結果。 -
First, the direction of fringe variation in the interference images is different with different intake duct, but in the same intake duct, the direction is the same. second, different intake duct has different rules to flow variation. third, the infinite width of interference fringe is visual, high precision, and easy to qualitative analysis, but the finite width of interference fringe is easy to judge the direction of fringe variation and to further detailed analysis
實驗結果表明，氣道不同，條紋的變化方向不同，但同一氣道在不同的流量下，條紋的變化方向是一致的；不同形狀的氣道對流量的敏感程度不同，對氣體旋流的擴散作用影響也有很大的差異；用無限寬條紋法得到的圖像直觀，靈敏度大，易於做定性的分析對比，而有限寬條紋法可以進行流體在運動方向的判別，更有利於詳細的分析研究。
