Simulation of 3-D Unsteady Flows in a Tubular Hydro-Turbine on DES

Abstract:

Taking a hydropower station as the research object, the establishment of a numerical model that contains the full passage Tubular Turbine is given. Based on the transient incompressible N-S equations, a three-dimensional unsteady flow research is conducted. Numerical simulation of steady turbulent flow channel is calculated as the initial condition, the detached eddy simulation (DES) and slip grid technology are adopted to simulate the static-dynamic interference in the unsteady turbulent flow, The instantaneous pressure distribution in full channel and vorticity distribution of the representive section are obtained, so the three-dimensional transient vortex structures in full flow channel of the hydraulic turbine are captured. These studies aiming to explore the mechanism for the formation of vortex-induced vibration of hydro-turbine are valuable for the engineering reference.
