Referat

Mazkur maqolada o‘zgaruvchan kesim yuzali kanallarda suyuqlik oqimining statsionar va nostatsionar harakati matematik modellashtirilgan. Tadqiqotda kichik g‘alayonlar usuli, Gurevich – Xaskind hamda Kuznetsov yondashuvlari asosida nostatsionar oqim parametrlarini aniqlash masalasi ko‘rib chiqilgan. Oqimning kompleks potensiali, tezlik va bosim maydonlarini aniqlash uchun analitik formulalar keltirilgan hamda erkin chegara uchun kinematik va dinamik shartlar hosil qilingan. Torayuvchi kanalda pulsatsiyalanuvchi oqimlarning xossalari tahlil qilinib, bosim amplitudasi va fazasining Struxal soniga bog‘liqligi o‘rganilgan. Tadqiqot natijasida kanalning siqilish zonasida yuzaga keladigan uyurmalik oqim parametrlarini hisoblashning analitik usuli ishlab chiqilgan hamda uyurmasiz oqimni ta’minlaydigan kanal shaklini aniqlash usuli taklif etilgan.
