Efficiency criterion of CFD-modelling for studying the ultrasonic flowmeters / Vitalii Roman, Fedir Matiko // Litteris et Artibus : proceedings of the 6th International youth science forum, November 24–26, 2016, Lviv, Ukraine / Lviv Polytechnic National University. – Lviv : Lviv Polytechnic Publishing House, 2016. – P. 199–200. – Bibliography: 4 titles.https://ena.lpnu.ua/handle/ntb/40752The paper presents a efficiency criterion of CFD-modelling for the research of ultrasonic flowmeters. He is a relative error of reproduction of mass flow rate in the i-th section 3D layout measuring pipeline.
