側出氣孔 的英文怎麼說
中文拼音 [zhāichūqìkǒng]
側出氣孔
英文
side air outlet-
By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves, it was found that there was intense turbulence in the flow fields around fixed - valve, there were eddy areas between valve side orifices and tray wall, there were eddies above the valves too, these led to the complex behaviors of gas perforating valve, these had a great effect on the gas - liquid mass transfer process. at the same time, in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer, it was very effective to change the fields of gas perforating valve by folding the edges of valve
通過對數值模擬得出的單閥和雙閥塔板的干板壓降及流場速度分佈分析對比后發現，固定閥周圍流場存在較強的湍動，閥側孔與塔板壁面區域以及閥體的上方空間存在明顯的渦流區，使氣體穿閥后的行為變得復雜，並對氣液傳質過程產生重大影響；模擬結果表明，為防止和削弱固定閥間的對沖造成的「死區」對傳質帶來的不利影響，通過折邊來改變氣體的氣路是非常有效的，模擬值與實驗值基本得到吻合。Methods : among these 32 patients with narrow nasal valve, 10 were operated with anterior inferior turbinectomy, 4 with deviation orthopedic of protruding trian gular outer cartilage ( 2 on the left, 2 on both sides ), 6 with bone - widen operation of osseous pyriform aperture ( 2 on the left, 4 on both sides ). the nasal ventilation before and after operation was observed
方法: 32例鼻瓣膜區狹窄患者，行下鼻甲前端切除術10例，鼻外側軟骨凸出矯正術4例（左側2例、雙側2例） ，骨性梨狀孔狹窄擴大術6例（左側2例、雙側4例） ，觀察手術前後鼻通氣改善情況以判定療效。Jet impingement cooling is an advantage method in heat transfer enhancement owing to its extremely high local heat transfer coefficient and simple structure. as regard as the combustor flame tube cooling structure is concerned, the impingement - converse convection - film composite cooling is an effective method, in this composite cooling structure, the impingement cooling problem could be modeled as impingement inside semi - confined channel
對于沖擊-逆向對流-氣膜復合冷卻的火焰筒結構而言，火焰筒壁面冷氣側的沖擊冷卻實質上是半封閉通道的沖擊冷卻，即沖擊射流從沖擊孔板噴出，沖擊到換熱靶面后形成壁面射流沿通道單方向流出。With fluid dynamic derived from marine mammals and subtle character lines stretching down the body ; the powerful imposing view of our canopy in flight is simply stunning
為了營造出古代羅馬戰神盔甲的雄壯氣勢，極度誇張霸氣進氣口的設計，搭配腮狀進氣側孔，飛行時氣流直達動力核心，增強熱能疏散。The article below deals with the mechanism research of this kind of machine, describing the structure and principle ; theoretically analyzing the data to derive formula ; tentatively proposing theory of radial flow between parallel plates for future design ; pores arrangement, i. e., longitudinal pores are equally spaced, horizontal pores bore size is preferred unequal and rows distance can be either equal or not but generally smaller than pores distance, and rows shall be odd numbers and are arranged symmetrical from the center row and bore size reduces gradually from the center row
本文對氣墊機作了機理研究，描述了氣墊機的結構型式及工作原理，對氣墊機的主參數作了理論分析，根據平行平板間的徑向流動理論，建立了計算模型，導出了計算公式，可作為氣墊設計理論的依據；提出了氣孔布置的原則：縱向孔間距相等較好，橫向孔徑不等為佳，橫向孔排距可以相等，也可以不相等，但一般小於孔間距。氣孔排數應為奇數，由中心兩側呈對稱布置，孔徑由中心向兩旁逐漸減小。分享友人
