Ushbu maqolada issiq suv va havo oqimlarining bevosita o‘zaro ta’siri sharoitida uyurmali kontaktli apparatda issiqlik almashinuvini jadallashtirish bo‘yicha kompleks eksperimental tadqiqot natijalari bayon etilgan. Tadqiqotning dolzarbligi energiya samaradorligini oshirish, ekspluatatsion xarajatlarni kamaytirish va issiqlik texnikasi hamda gaz tozalash tizimlarining ekologik xavfsizligini ta’minlashga qo‘yilayotgan talablarning ortib borishi, shuningdek sanoatning barqaror rivojlanish tamoyillariga bosqichma-bosqich o‘tishi bilan belgilanadi. Ishning asosiy maqsadi gidrodinamik parametrlar, fazalarning massaviy sarflari nisbatlari hamda oqimlarning aylanish jadalligining issiqlik berish koeffitsienti, issiqlik quvvati va apparatning umumiy issiqlik samaradorligiga ta’sirini miqdoriy jihatdan aniqlashdan iborat.
Tadqiqot doirasida gaz va suyuqlikni tangensial yo‘nalishda kiritish orqali barqaror uyurmali rejimini va fazalararo kontakt yuzasini hamda yuqori turbulentligini ta’minlovchi eksperimental qurilma ishlab chiqildi va amaliy sinovdan o‘tkazildi. Olingan natijalar Nusselt va Reynolds mezonlari asosida, shuningdek bug‘lanish, kondensatsiya va havoning namlik miqdori o‘zgarishini hisobga oluvchi issiqlik balansi tenglamalari yordamida qayta ishlangan. Tajribalar Reynolds sonining keng diapazonida va turli L/G nisbatlarida olib borildi, bu esa issiqlik uzatish jarayonidagi barqaror qonuniyatlarni aniqlash imkonini berdi.
Aniqlanishicha, gaz Reynolds soni 45360 dan 97253 gacha oshganda Nusselt soni 2300 dan 15700 gacha ortadi, bu esa turbulentligining sezilarli kuchayishi va fazalararo sirtning jadal yangilanishini ko‘rsatadi. Sug‘orish zichligining ortishi suyuqlik yupqa qatlami tez yangilanishi va kontakt yuzasining kengayishi hisobiga is-siqlik almashinuvini qo‘shimcha ravishda jadallashtiradi. Olingan natijalar energiya tejamkor uyurmali issiqlik almashinish apparatlari hamda nam gaz tozalash qurilmalarini loyihalash, optimallashtirish va mavjud sanoat qurilmalarini modernizatsiya qilishda qo‘llanishi mumkin.
