Ushbu maqolada quvur ichida suyuqlik oqimi jarayonida yuzaga keladigan gidravlik qarshilik koeffitsientini aniqlash masalasi o‘rganilgan. Tadqiqot Nikuradze tomonidan o‘tkazilgan klassik tajribalar asosida olib borildi. Gidravlik qarshilik koeffitsienti analitik usullar — Puazeyl, Blazius va Alshul formulalari yordamida hisoblandi. Shuningdek, ushbu jarayon COMSOL Multiphysics dasturining CFD moduli orqali turbulent k-e modeli orqali sonli modellashtirildi. Analitik va sonli hisoblash natijalari o‘zaro solishtirilib, ularning aniqlik darajasi va qo‘llanish chegaralari baholandi. Tadqiqot natijalari quvur tizimlarini loyihalashda energiya yo‘qotishlarini kamaytirish va gidravlik hisoblarning ishonchliligini oshirishga xizmat qiladi.References
