The main reason is the huge computational resources required to accurately simulate the vortex rope.
#Hydro turbine design software software
GE Energy engineers selected Ansys CFX software from Ansys in Pennsylvania, US, as their modelling tool. The flexibility of the technique makes it possible to solve these equations in very complex spaces, unlike simpler modelling methods that are sometimes used for turbine design.

CFD is a powerful technique that provides an approximate solution to the coupled governing fluid flow equations for mass, momentum and energy transport. This information makes it possible to design the turbine in order to reduce the magnitude of the vortex rope and to withstand the remaining pressure fluctuations without any fatigue damage.Ĭomputational fluid dynamics (CFD) is the obvious tool of choice for simulating flow within a turbine. It is not possible to measure the vortex rope in an actual operating turbine so engineers designing these systems need a way to simulate the frequency, pressure pulsation amplitude, and other parameters under various operating conditions and turbine geometries.

This phenomenon is especially severe when the frequency of the oscillations of the vortex rope matches the resonant frequency of the turbine or of the circuit. The vortex rope creates high-pressure unsteady fluctuations on the walls of the draft tube, which could lead to fatigue damage over time. As the incoming swirling flow decelerates in the diffuser cone, a hydrodynamic instability arises that looks like a rope twirling around in the draft tube, hence the name vortex rope. This creates special challenges in hydro power turbines because at partial loads these turbines often exhibit strong swirl at the runner outlet. ONE of the most distinguishing characteristics of today’s deregulated power market is its variable demand, which means that profitability often depends on the ability to efficiently operate at partial loads. Computational fluid dynamics software is being used by researchers to accurately simulate the position and pressure fluctuations of a draft tube rope in a hydro plant
