噴嘴壁 的英文怎麼說
中文拼音 [pēnzuǐbì]
噴嘴壁
英文
nozzle wall-
Low frequency micro - vibration causes the micro - fluid to produce uniform dispersion and injection which carried out a hydrophobization treatment on the inner wall of micro - nozzle, thus eliminated the spontaneous flowing of micro - fluid inside the micro - nozzle due to wet ting effect so as to let the micro - injection be provided with a digitalized and volume controllable character
壓電陶瓷低頻微振動使得微流體產生均勻的離散和噴射；對微噴嘴內壁進行疏水化處理，從而消除微流體由於濕潤作用在微噴嘴內部的自發性流動，使得微噴射具有數字化量可控的特徵。The shearing layer is carried by the jet and the eddy is formed because of the instability and selective amplification of shearing layer which will propagate to the downstream. as the eddy impacts the impinging wall, a wave of pressure disturbance with certain frequency is induced. this wave then propagates to the upstream with high speed, and results in the overlap and amplification of the waves when the frequencies of them are close with each other
當前噴嘴流束中的不穩定擾動波在穿過腔內的剪切層時，剪切層對其有選擇放大作用，形成渦環結構，剪切流動中渦環與碰撞壁撞擊，在碰撞區域產生壓力擾動波並向上游反射，在上游剪切層分離處誘發新的擾動的產生，當新擾動與原擾動匹配時，射流上游就被不斷地受到周期性激勵，腔內就產生流體自激振蕩並在後噴嘴出口形成脈沖射流。The resultant precipitates deposited on pipe walls and in orifices and sprinklers can completely plug the irrigation system
產生的沉澱沉積于管壁、滴水孔和噴嘴上，完全阻塞整個灌溉系統。A laboratory - scale gasoline injector deposit simulator was developed to simulate deposit formation, and the fourier transform infrared ( ftir ) technique was used to analyze the deposit formation mechanism under various wall temperature
摘要建立了實驗室尺度的沉積物生成模擬裝置，並嘗試以ftir傅里葉轉換紅外線光譜法分析沉積物生成的化學機理，以探討不同壁面溫度下的噴嘴沉積物生成過程。分享友人
