چکیده مقاله :

این پژوهش به منظور بررسی اثر سرعت باد و ارتفاع پایه آبپاش بر ضریب یکنواختی توزیع آب در شهرستان اهواز انجام شد. آب پاش های مورد استفاده شامل ژاله3، ژاله5 و کمت به ترتیب با دبی 11/2، 4 و 3 مترمکعب بر ساعت و قطر پاشش 30، 40 و 35 متر با ارتفاع های پایه آب پاش 0/1، 4/1، 8/1 و 2/2 متر و تحت سرعت های باد ملایم تا متوسط و شدید بودند که در یک سیستم آبیاری بارانی کلاسیک ثابت با آب پاش متحرک مورد بررسی قرار گرفتند. در دامنه سرعت باد ملایم تا متوسط، با افزایش ارتفاع پایه آب پاش از 100 تا 140 سانتی‌متر، ضریب یکنواختی آب افزایش و از ارتفاع پایه آبپاش 140 تا 220 سانتی‌متر، ضریب یکنواختی کاهش یافت. در سرعت باد شدید با افزایش ارتفاع پایه آبپاش از 100 تا 220 سانتی‎متر، کاهش ضریب یکنواختی آب مشاهده شد. در آرایش 18 × 18 متر، ضریب یکنواختی توزیع آب برای آبپاش ژاله5 بیشترین میزان و برای آبپاش ژاله3 کمترین میزان مشاهده شد. در نهایت، ارتفاع پایه آبپاش 140 سانتی‎متر در سرعت باد ملایم و ارتفاع پایه آبپاش 100 سانتی‎متر در سرعت باد شدید به عنوان مناسب‎ترین ارتفاع پایه آبپاش طرح انتخاب گردیدند.

چکیده انگلیسی:

In this study, the effect of wind speed and riser height on the uniformity coefficient of water distribution in Ahvaz city was investigated. Sprinklers were including Zhaleh 3, Zhaleh 5, and Komet with discharges of 2.11, 4 and 3 m3/h and spraying diameters of 30, 40 and 35 m, respectively and riser heights of 1.0, 1.4, 1.8, and 2.2 m under mild to moderate and severe wind speeds in a solid set system with portable sprinklers were investigated. In the mild to moderate wind speed range, increasing in riser height from 100 to 140 cm, the uniformity coefficient of water distribution increased and in riser height rage from 140 to 220 cm, the uniformity coefficient decreased. In the severe wind speed, increasing in riser height from 100 to 220 cm, the uniformity coefficient decreased. The uniformity coefficient of water distribution in the layout of 18 × 18 m for sprinkler Zhaleh 5 was in the highest and for sprinkler Zhaleh 3 was in the lowest value. Finally, the riser height of 140 cm in the mild wind speed range and the riser height of 100 cm in the severe wind speed range were selected as the best riser heights.
