  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。
  2. It is shown that the fin efficiency, air flow - rate, and fin performance are significantly decreased while pressure of the air side is increased when frosting occurs at the exchanger

    研究發現，換熱器結霜引起了翅片效率、空氣流通率及翅片性能的顯著降低，同時還伴隨著空氣側壓力降上升。
  3. Air wide pre. drop

    空氣側壓降
  4. The performances such as air flow, airside pressure drop, waterside heat exchange and power consumed by compressor vs. frosting time under different condition, were simulated and analyzed by using the ashpwch model developed

    採用該模型對機組在不同工況下的性能進行了模擬分析，得到了風量、空氣側壓降以及水側換熱器換熱量、壓縮機的軸功率等隨結霜時間的變化。
  5. Concentric jacket pipe surrounded the test condenser. steam was generated in the boiler, flowed upward to the inlet of connection pipes, then flowed downward into the condenser tube, the cooling water flowed countercurrently through the annulus. the experiment covered the range of the pressure 1. 0 ~ 3. 0bar, heating power 2. 0 ~ 15. 0kw, steam mass flow rate 0. 001 ~ 0. 004kg / s, air mass flow rate 0. 0 ~ 0. 00163kg / s, and cooling water temperature 20 - 60 ?

    在系統壓力為0 . 1 0 . 3mpa ，加熱功率為2 15kw ，蒸汽質量流量為0 . 001 0 . 004kg s ，空氣質量流量為0 . 0 0 . 00163kg s ，二次側冷卻水溫度20 60的范圍內，系統研究了豎直下降管內含有空氣的蒸汽冷凝特性，獲得了不同壓力、不同空氣含量和不同加熱功率下，冷凝段的溫度分佈和局部熱流密度的數據。
  6. A transverse secondary circulation is produced by the coupling of high and low jets, while the sinking branch of the secondary circulation providing the dynamic conditions for the dry intrusion air. during the period of the heavy rain process, dry intrusion descends southward along the intense constant potential temperature lines, which promotes the lower cyclone. in addition, the pouring of upper - level dry air not only decreases ground temperature behind the front but also increases surface pressure and velocity

    由於高、低空急流耦合，在高空急流中心左側產生的下沉運動和高空急流中心右側、低空急流左側產生的上升運動在鋒面上形成一次級環流，次級環流的下沉支運動為對流層高層干空氣和高位渦的下傳提供了動力條件；進一步研究發現，干侵入沿相當位溫密集帶向南向下伸展，引起對流層低層氣旋性渦度的發展；此外，高層乾冷空氣向下注入，導致地面溫度降低、氣壓升高、風速加大、低層輻合增強、上升速度加大，從而促進了新的對流運動，引起降水增強。
