Tuz gradientli quyosh hovuzlarida sodir bo‘ladigan issiqlik jarayonlarini hovuz chuqurligi bo‘yicha tavsiflashga
mo‘ljallangan bir o‘lchamli nostatsionar matematik model ishlab chiqilgan. Modelda quyosh nurlanishining suv-tuz
muhitida yutilishi, konveksiya bo‘lmagan zonadagi issiqlik o‘tkazuvchanligi, hovuz sirtidagi konvektiv, radiatsion va bug‘lanish
bilan bog‘liq issiqlik yo‘qotishlari, shuningdek, hovuz tubidan tuproq qatlamiga uzatiladigan issiqlik oqimi kompleks
tarzda hisobga olingan. Modelning fizik asosini issiqlik o‘tkazuvchanlik tenglamasi, energiya balansi, Buger–Lambert
qonuni hamda chegaraviy shartlar tizimi tashkil etadi. Hisoblash natijalari konveksiya bo‘lmagan zona qalinligi 0,6–1,2 m
oralig‘ida bo‘lganda pastki konvektiv zonada issiqlikni samarali akkumulyatsiya qilish imkoniyati ortishini ko‘rsatdi. Taklif
etilgan model quyosh hovuzlarini muhandislik jihatidan loyihalashda termik samaradorlikni, qatlamlar barqarorligini va
issiqlikni saqlash muddatini oldindan baholash uchun ilmiy-amaliy asos bo‘lib xizmat qiladi
