dry pressure drop 中文意思是什麼
dry pressure drop
解釋
氣液接觸塔無迴流時的壓力損失-
At first, in the process of experiments, it were measured that dry plate pressures drop and point pressures in the flow fields around the single fixed - valve and double fixed - valves under different velocities by using of pitot tube. after that point pressure was transformed to point velocity, two dimensions flow plane of flow fields around fixed - valve were plotted to observe the difference between of the fixed - valve tray with fold edges and the common rectangular fixed - valve tray on the distributions of flow fields and pressures, to provide comparisons and refer - rence for cfd simulation
在實驗中，利用測速管等儀器對在不同速度下的單閥和雙閥固定閥周圍的流場進行了點壓力測量，然後把點壓力轉化為點速度后繪出固定閥周圍流場的二維流線圖，同時測定了塔板的干板壓降，來考察新型固定閥帶折邊后對流場分佈和壓降的影響，為隨后的數值模擬提供對比和依據。 -
The pressure drop of the compound tray can be regarded as consisting of dry plate pressure drop, clear liquid resistance, liquid surface tension resistance, and packing pressure drop. the model that has established can fairly predict the pressure drop of the compound tray, the value calculated by the model compared with that detected by experiment is less than 20 %
復合塔板的壓降可認為由干板壓降、清液層阻力、填料層壓降和克服液體表面張力的壓降四部分組成，所建立的壓降計算模型，能較好地預測復合塔板的壓降，計算值與實驗值誤差在20以內，可用於工程設計。 -
For improving the flow manner on the plate, the downcomer apron was modified from straight shape to trapezoidal shape. the hydrodynamics performance of the modified ctst tray, for example, the pressure - drop of dry tray and wet tray, liquid weeping and vapor entrainment etc were measured
對優化后的塔板流體力學性能進行了測試，分別測量了不同氣液流量下的干板及濕板壓降、霧沫夾帶量和漏液量等數據，並與改造前的塔板流體力學性能進行了對比。
