Ushbu tadqiqot kapillyar tuzilmali g‘ovak membrana bilan integratsiyalangan quyosh energiyasida ishlovchi chuchutish qurilmasi uchun kompleks uch o‘lchovli sonli modelni taqdim etadi. Boshqaruvchi tenglamalar, jumladan, issiqlik almashinuvi, kapillyar ta’sirida yuzaga keluvchi massa almashinuvi, Darcy-Brinkman impuls tenglamalari hamda Hertz-Knudsen formulasi asosidagi fazalararo bug‘lanish jarayonlari chekli hajmlar usuli (FVM) yordamida 6,4 × 106 nazorat hajmlaridan iborat to‘rda bir vaqtda yechildi va ikkinchi tartibli L2 xatolik 0,28% ga erishildi. G‘ovaklik (φ=0,20-0,90) va kapillyar diametri (d=10-200 mkm) bo‘yicha parametrik optimallashtirish natijasida φ=0,65 va d=35 mkm qiymatlarda eng yaxshi ekanligi aniqlanib, maksimal issiqlik samaradorligi η=83,7 ± 2,2% hamda kunlik chuchuk suv ishlab chiqarish 14,8 ± 0,8 kg/m2·kun ga yetgani qayd etildi (1000 W/m2 quyosh nurlanishi sharoitida), bu an’anaviy tekis absorberlarga nisbatan 97,9 % ga yuqori ko‘rsatkichni tashkil etadi.
Kapillyar strukturali g‘ovak membrana (CPM) asosidagi quyosh chuchitgich qurilmasi Darcy-Brinkman-Forchheimer 3D matematik model yordamida tadqiq etildi. Issiqlik uzatish, massa almashish va kapillyar momentum tenglamalari bir vaqtda yechildi. Adaptiv chekli hajmlar metodi (FVM) 6,4×106 boshqaruv hajmli tarmoqda ikkinchi tartibli aniqlikda amalga oshirildi. G‘ovaklilik φ = 0,20–0,90 va kapillyar diametr d=10-200 μm oralig‘ida parametrik optimallashtirish o‘tkazildi. Model natijalari laboratoriya tajribalari bilan taqqoslanib tasdiqlandi. Bug‘lanish kinetikasi Hertz-Knudsen tenglamasi orqali, tuz transporti esa reaktiv adveksiya-diffuziya tenglamasi orqali modellashtirildi.
Optimal konfiguratsiya φ=0,65 va d=35 μm bo‘lganda issiqlik samaradorligi η=83,7 ± 2,2% ga, kunlik hosildorlik esa ga yetdi. Bu ko‘rsatkichlar an’anaviy va yassi qurilmaga nisbatan mos ravishda 97,9 % va 185 % yuqori bo‘ldi. Sonli model tajriba ma'lumotlari bilan MAE=1,9% va R2=0,9974 aniqlikda mos keldi. Kapillyar oqim konsentratsiya polyarizatsiyasini 44,3% ga kamaytirdi va erigan moddalarni 62 ± 12 mg/L ga tushirdi, bu WHO standartidan 8 baravar past. Optimallik cho‘qqisi φ≈0,645 da irradiance qiymatidan mustaqil ravishda saqlanib qoldi. Kapillyar qurilma an’anaviy absorberga nisbatan tuz qoldig'ini 480 dan 62 mg/L ga kamaytirib, suv tozaligini tubdan yaxshiladi.
