Quality of wind tunnel relates not only to airflow shape and outside frame but also subjected to the control system of electromotor. the rotate speed of fans and the speed press of flow field at experimental segment are the primary parameters for control
風洞流場的品質除與風洞氣動外形及內部構造有關外，關鍵取決于風洞風扇電機控制系統，其調節的主要參數是風扇電機的轉速和試驗段流場的速壓。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。Since the old type of fl - 8 cannot meet the new requirement, we have to rebuild the control system of electromotor
由於fl - 8風洞建成較早，其風扇電機控制系統已不能滿足大量實驗的要求。
