This study aims to propose an experimental and numerical framework to examine the
sediment erosion in the two components of Francis turbine (FT) namely guide vanes and …

The design of the Francis turbine aims to maximize its performance in terms of efficiency.
This design approach has overlooked effects on the turbine due to sediment erosion for …

Hydropower stations are an important source of clean energy, usually operating in sandy
water flow, and the turbine wheels may suffer severe wear and tear. In addition, during the …

Secondary flows in Francis turbines are induced by the presence of a gap between guide
vanes and top–bottom covers and rotating–stationary geometries. The secondary flow …

A clearance gap (CG) between guide vanes (GVs) and facing plates exists at both ends of a
Francis turbine and allows the opening angle to be adjusted for varying operating …

Hydraulic turbine runners experience high excitation forces in their daily operations, and
these excitations may cause resonances to runners, which may induce high vibrations and …

Sediment erosion is a negative phenomenon for the water turbine. The purpose of this paper
is to study the effect of the guide vane opening on the particle motion and sediment erosion …

In this paper, the Eulerian–Lagrangian method and Tabakoff erosion model are used to
study the solid–liquid two-phase flow in a Francis turbine. Through the analysis of the overall …

Sediments flowing with water in the Himalayan Rivers of Nepal erodes the components of
the turbine heavily. The design of hydraulic turbines prioritizes the hydraulic performance of …

The research works introduce in this chapter with background and a statement of the
problem. After designing research questions, scopes and limitations, research objectives …
