چکیده
Today, due to the severe decline of water resources and the crisis of freshwater scarcity, the use of new methods for water production and recovery is of particular importance. The presence of high humidity and fog in many parts of the world has the potential for water collection. In this research, using of super-hydrophobic/hydrophilic surfaces for water harvesting from the humid air as a simple method with minimum energy consumption is investigated. The material of the plates, the use of meshed plates, the angle of plate placement, and the distance from the steam flow were investigated for the cold and hot steam flows. The results of the experiments revealed that the polymeric plate has an acceptable performance of 893.062 g/m2.h, and they can be used because of its lightness, cheapness, and easy malleability. The results of hot and cold steam systems showed that the plates with one face exposed to hot steam and one face exposed to the environment perform better compared to ultrasonic cold steam, and the plate placement at an angle of 75 degrees with the horizon can increase the water harvesting efficiency 3 times compared to the plate with 90° angle. Plates coated with dye material obtained better results than simple hydrophilic plates in the hot steam system due to their super hydrophobic/hydrophilic properties. Among the surfaces used, the hydrophobic aluminum meshed plate and solid plate were the plates with the best performance that, achieved a water harvesting performance of 55 g/m2h.

پوشش بر پایه رنگ رزین آلکیدی روی سطوح به منظور تولید خواص آب دوست/آب گریز و افزایش عملکرد برداشت آب از مه یا بخار
چکیده [English]
امروزه با توجه به کاهش شدید منابع آب و بحران کمبود آب شیرین، استفاده از روش های نوین برای تولید و بازیافت آب از اهمیت ویژه ای برخوردار است. وجود رطوبت بالا و مه در بسیاری از نقاط جهان پتانسیل جمع آوری آب را دارد. در این تحقیق استفاده از سطوح فوق آبگریز/آب دوست برای برداشت آب از هوای مرطوب به عنوان روشی ساده با حداقل مصرف انرژی مورد بررسی قرار گرفته است. جنس صفحات، استفاده از صفحات مشبک، زاویه قرارگیری صفحه و فاصله از جریان بخار برای جریان بخار سرد و گرم بررسی شد. نتایج آزمایشات نشان داد که صفحه پلیمری دارای عملکرد قابل قبول 062/893 گرم بر مترمربع ساعت بوده و به دلیل سبکی، ارزانی و چکش خواری آسان قابل استفاده است. نتایج حاصل از سیستم های بخار سرد و گرم نشان داد که صفحات با یک وجه در معرض بخار داغ و یک وجه در معرض محیط در مقایسه با بخار سرد اولتراسونیک عملکرد بهتری دارند و قرارگیری صفحه در زاویه 75 درجه با افق می تواند باعث افزایش آب شود. راندمان برداشت 3 برابر نسبت به صفحه با زاویه 90 درجه. صفحات پوشش داده شده با مواد رنگزا به دلیل خواص فوق آبگریز/آب دوست، نتایج بهتری نسبت به صفحات آبدوست ساده در سیستم بخار داغ به دست آوردند. در بین سطوح مورد استفاده، صفحه مشبک آلومینیومی آبگریز و صفحه جامد صفحات با بهترین عملکرد بودند که عملکرد برداشت آب 55 گرم در متر مربع را به دست آوردند.
