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。 -
In this paper, according to the need of developing new style column, new style fixed - valve tray - rectangular fixed - valve tray with fold edges and common rectangular fixed - valve tray were studied from experiments and cfd simulation
本文針對開發塔設備新類型的需要，從實驗和cfd模擬兩方面對新型的固定閥塔板-帶折邊矩形固定閥塔板以及普通的矩形固定閥塔板進行了研究。
