Proposte di tesi
Experimental Investigation of a Pump-Turbine at Off-Design Operating Conditions in Generating Mode
In the present study, a reduced scale model of a low specific speed radial pump-turbine will be investigated to identify the onset and development of flow instabilities. Wall pressure measurements in the stator will be performed with the help of miniature piezoresistive sensors to analyse low frequency component at runaway and the instability sources.

Hydrodynamics of Pump-Turbine at Off-Design Operating Condition in Generating Mode
Numerical flow investigations of a radial pump-turbine will be performed under off-design operating conditions, involving speed no load, runaway and “S-shape” turbine brake curve.

Hydrodynamics of Power Pumps at Off-Design Operating Conditions
In the present study, a low specific speed radial pump has to be investigated to identify the onset and development of flow instabilities.

Experimental Investigation of a Pump-Turbine at Off-Design Operating Conditions in Pump Mode
The focus will be put on the generating instability at off-design conditions due to the rotor stator interactions. Wall pressure measurements in the stator will be performed with the help of miniature piezoresistive sensors to analyse low frequency component at runaway and the instability sources.

Francis Turbine Design a New Approach
This thesis will investigate a new methodology for the design optimization of hydraulic runner blades. The originality of the methodology comes from the geometric definition of the blade load, which uses parametric surfaces instead of a set of profiles.

Hydrodynamics of the free surface flow in Pelton turbine buckets
The flow in Pelton turbines has to be analyzed with such detail to understand the physics of the initial jet/bucket interaction and the jet cut process.

Parametric Design of a Pelton Bucket
The present thesis will be focused on the parametric design of a Pelton bucket. The runner geometry will be parameterized by means of an inverse design method.

Design and Optimization of Unconventional Profiles to Improve the Self-Start Capability of the H-Darrieus Turbine
This thesis will investigate a new series of profiles. On the basis of this study, an optimum configuration will be designed which results in a higher self-start capability of the runner, while maintaining a high level of the Power Coefficient.

Start-up Analysis of a Vertical Axis Wind Turbine
Different approaches to describe the self-start of an H-blade Darrieus rotor will be considered and compared in the present work.

Field Test on a Self-Starting H-Darrieus Turbine
Experimental/numerical analyses of a new self starting Vertical Axis Wind Turbine.

Hydrodynamics of the Banki Mitchell Turbine
The aim of this project will be to perform the simulation of the flow in a Banki Mitchell turbines using a SPH code. The velocity profile will be compared with CFX results.

Banki Mitchell Turbine Blade Optimization
The present thesis will be focused on the optimization of the Banki Mitchell impeller. The runner geometry will be optimized by a particle swarm optimization (PSO) method, while CFD analyses will be performed to assess the performance of different design configurations.
