罩蓋
英文
shroud-
Excessive lint accumulation at the sides of under casing
罩蓋側邊的棉回花聚集太多。Because of its special structure, the high velocity flow under the shield, big vortex and upcast flow behind the shield will affect the spray drift. if these situations could be changed, the drift can be reduced further
但由於該罩蓋的結構特點，其下方產生較大速度的運動氣流和罩蓋後部產生的渦流以及上旋氣流，將直接影響霧滴的飄失。A slot was cut in the back plate of the double - foil shield to improve the flow field with air diversion method. the flow field and droplets trajectory near the shield are simulated in wind tunnel by fluent software to analyze the wake flow affecting the spray drift. from simulation, the improved shield spray in reducing drift is better than double - foil shield spray and conventional spray in six types of wind velocity
本文採用導流法在雙圓弧罩蓋上開口，利用fluent模擬分析和比較罩蓋噴霧流場，並模擬該流場下的霧滴運動軌跡來分析霧滴的飄失性，模擬結果表明：結構改進后的罩蓋噴霧流場得到改善，其減少霧滴飄失的效果好於原罩蓋，更優于常規無罩蓋噴霧。The results also show that the filtration effect is improved by the sand coated with metal oxide, and coagulation which is combined with filtration can enhance the efficiency of algae removal
對水樣進行過濾處理，發現用金屬氧化物進行罩蓋過的石英砂對其過濾效果有所提高。The segments up from dam no. 3 with the excellent temperature regimes, various habitat types and satisfactory tree coverage can be classified as superior habitats for the formosan landlocked salmon
三號壩以上無論是水溫、棲地類型豐富度、罩蓋度均可歸類為良好棲地，建議持續上游放流工作，擴大上游族群。When treatment is complete, the flap is repositioned and placed back to its original position. it seals and heals naturally

進一步的數值模擬顯示鉸鏈不再發生斷裂，罩蓋變形模式合理。At present, among the researched structures, the double - foil shield is the best one during experiments
目前國外試驗研究的罩蓋結構中，雙圓弧罩蓋效果最好。Reciprocating internal combustion engines - vocabulary of components and systems - part 1 : struture and external covers
往復式內燃機零部件和系統術語第1部分:固定件及外部罩蓋Never forget to put on the lens hood after you use the camera
每次照相機用完以後，千萬不要忘記把遮光罩蓋上。So the shield structure was improved to change the flow field, and experiments will be conducted to validate the effect in reducing spray drift
因此，作者提出雙圓弧罩蓋結構的改進方法，並進行減少霧滴飄失的對比試驗研究。In order to validate the correctness of the simulation, the flow velocity of x vector is measured to compare the flow field between the simulation and the experiment in wind tunnel. the results indicate that the flow field is improved and more stable than the original shield flow field. the tendency between the improved shield and the original shield from simulation is consistent with the tendency from experiments
開口罩蓋流場由於相對穩定，模擬和試驗的測點流速平均相對誤差為15 ，未開口罩蓋流場中由於渦流影響較大，平均相對誤差為22 . 45 ；同時驗證了結構改進前後罩蓋流場的模擬比較結果和試驗比較結果的趨勢是一致的。Mechanical shield spray has good effect in reducing spray drift with low cost, simple structure. the structure is the key point
機械式罩蓋噴霧是一種結構簡單、價格便宜和減少霧滴飄失效果好的噴霧方法，其中罩蓋結構起著關鍵的作用。Experimental constants include : ambient temperature 291k ~ 301k, rh 15 % ~ 21. 2 %, wind velocity 3. 2m / s at the nozzle position and horizontal to the spray fan, others are same as the fore experiment. the tendency of the two experiments results is consistent with the tendency from simulation. that indicate the improved shield spray is better than the original shield spray in reducing spray drift, and also more better than conventional spray without shield
風洞試驗參數：噴霧藥液為含1 bsf的水溶液，風速1 . 4m s ，風向垂直於噴霧扇面，溫度281k 288k ，相對濕度rh9 20 ；室內試驗參數：噴霧藥液為含2 bsf的水溶液，噴頭處風速為3 . 2m s ，風向平行於噴霧扇面，溫度291k 301k ，相對濕度rh15 21 . 2 ；分別在噴頭下風向噴幅外的空中和地面布點收集飄失和飄移沉積的霧滴量，作為評價減少霧滴飄失效果的指標：試驗結果表明：改進后的罩蓋噴霧減少霧滴飄失的效果好於雙圓弧未開口罩蓋噴霧，常規無罩蓋噴霧的霧滴飄失量大於開口罩蓋噴霧。分享友人
