Studying laminar flows of power-law fluids in the annular channel with eccentricity
The paper deals with numerical and experimental investigation of non-Newtonian flow of modeling drilling fluids in the annular channel. The Reynolds number was ranged from 100 to 1500. The parameters of the power-law model ...
Numerical and experimental study of the pressure pulsations at the free discharge of water through the turbine
The free discharge through the turbine is applied in the course of construction of hydro power plant or in case of excessive water inflow during floods or emergency situation. The experimental and numerical investigation ...
Numerical investigation of flow structure and pressure pulsation in the Francis-99 turbine during startup
We performed numerical simulation of flow in a laboratory model of a Francis hydroturbine at startup regimes. Numerical technique for calculating of low frequency pressure pulsations in a water turbine is based on the use ...
Francis-99 turbine numerical flow simulation of steady state operation using RANS and RANS/LES turbulence model
We performed numerical simulation of flow in a laboratory model of a Francis hydroturbine at three regimes, using two eddy-viscosity- (EVM) and a Reynolds stress (RSM) RANS models (realizable k-epsilon, k-ω SST, LRR) and ...
