Mathematical modeling of low-frequency pressure fluctuations in hydroturbine ducts
The results of the modeling of unsteady three-dimensional flows in the hydroturbine ducts of two high-head hydroelectric stations are presented. The flow structure behind the turbine wheel is analyzed and its effect on the ...
Single-Fluid Model of a Mixture for Laminar Flows of Highly Concentrated Suspensions
A model of laminar flow of a highly concentrated suspension is proposed. The model includes the equation of motion for the mixture as a whole and the transport equation for the particle concentration, taking into account ...
Numerical Investigation of Three-dimensional Cavitating Flow around a Guide Vane of a Water Turbine
The results of numerical simulation of cavitating flow around the experimental model of a guide vane of a water turbine are given. The possibilities of the detached eddy simulation (DES) method for calculating the flow ...
