ZAMONAVIY DIFFUZER DIZAYNNI: KINETIK ENERGIYANI BOSIMGA SAMARALI AYLANTIRISH
Main Article Content
Abstract
So'nggi paytlarda to'g'onlarning quyi oqimida qolgan energiyadan foydalanish sezilarli bo'ldi. Suv oqimida mavjud bo'lgan kinetik energiya juda katta bo'lgani uchun e'tibor beriladi. Bu ish ishlab chiqilgan. Gorizontal eksa gidrokinetik yordamida to'g'onlarning quyi oqimida energiya olishini aniqlash uchun yangi tadqiqot diffuzorli turbina. Ushbu baholash Tucurui to'g'onidagi dala ma'lumotlaridan foydalanadi, bu erda 2,35 m / s oqim tezligi eng yuqori energiya qazib olinishi mumkin bo'lgan tezlikdir. Bu holda, gardishli konus bilan o'ralgan diametri 10 m bo'lgan 3 qanotli gidrokinetik turbina diffuzor, simulyatsiya qilingan. Hisoblash suyuqlik dinamikasi yordamida raqamli modellashtirish amalga oshirildi. Reynolds o'rtacha hisoblangan Navier-Stoks formulasidan foydalanib, siljish stressini tashish kabi turbulentlik modeli. Natijalar eksperimental va nazariy ma'lumotlarga yaxshi mos keladi. Bundan tashqari, diffuzer ta'siri ostida turbinaning quvvat koeffitsienti bo'lishi mumkin 5,4 uch tezligi nisbati uchun taxminan 55% ga oshadi va quvvat chiqishi taxminan 1,5 baravar oshdi. Amazon mintaqasida to'g'onlarning quyi oqimida o'rnatilgan turbinalar, bu tadqiqot shu sababli dolzarbdir gidrokinetik turbinalardan turbinali va vertedli turbinalarni ishlatish uchun muqobil sifatida foydalanishni o'rganadi. Ushbu muqobil ehtiyoj tufayli yuzaga keladigan atrof-muhitga boshqa ta'sirlardan qochishga yordam beradi.
