Dvofazno strujanje pri povratnom hidrauličkom udaru

Abstract

U okviru doktorske disertacije je razvijen numerički postupak za proračun dvofaznog strujanja pri povratnom hidrauličkom udaru, koji se često javlja u hidroenergetskim postrojenjima. Korišćen je homogeni model jednofaznog i dvofaznog stišljivog strujanja u kome su strujni i termodinamički parametri dobijeni usrednjavanjem parametara tečne i parne faze po jedinici mase...

Numerical procedure for calculating the two-phase flow in the reverse waterhammer on hydropower plants, which often occurs in hydropower plants, is developed and presented in this dissertation. A homogeneous model of single-phase and two-phase compressive flows is used in which the flow and thermodynamic parameters are obtained by averaging the parameters of the liquid and gas phase per unit mass. It is assumed that the gas and liquid phase are in the velocity and thermal equilibrium, and that the flow of the two-phase mixture is isenthalpic...
