  1. 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。
  2. The pore velocity is the velocity with which a tracer moves through a porous medium.

    是示蹤元素穿隙介質的
  3. In this paper, firstly the macro parameter of the series connection app was comprehensively analyzed, among which the trajectory location of the bullet emission and the terminal velocity of the bullet were mainly analyzed, and the feasibility of the series connection app to cope with explosive reactive armor was demonstrated. and then the macro design about the head of the series connection app was made, among which a particular analyse about the bullet " s launching process was made, from which we concluded the relation between the thickness of the airproof loop and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the burning rate of the powder and the relation between the length of the bullet and the maximum pressure of the emission hole and the relation between the length of the bullet and the emitting time of the bullet, and the reasonable str ucture of the head of the carrier and bullet were designed, then the intensity of the head of the carrier was checked out using of the software of ansys

    本文首先對子母式穿甲彈總體參量作了全面的計算分析,其中主要分析了子彈射出的彈道位置和必要的子彈著靶,論證了子母式穿甲彈對付爆炸式反應裝甲的可行性,然後對子母式穿甲彈彈頭部進行了總體設計,其中主要對子彈的發射過程進行了詳細的分析,得出了母彈彈頭部發射內閉鎖環厚與子彈飛離母彈的關系、子彈長與子彈飛離母彈的關系、子彈長與火藥燃燒率的關系、子彈長與母彈彈頭部發射內最大壓力的關系以及子彈的長與子彈發射所需時間的關系,設計出了合理的母彈彈頭部結構和子彈的結構,並利用ansys有限元分析軟體對母彈彈頭部的強進行了校核。
