Scope

Hydraulic Turbines

This session invites the presentations related to hydraulic turbines especially on “Design and optimization”, “Multidisciplinary design optimization”, “Unsteady flow phenomena”, “Performance prediction and enhancement” and “Erosion and cavitating flows.” The final structure of the session will be determined based on the accepted presentations.

Pumps

Topic areas covered by this session include the followings : “Design techniques” including computational methods, “Applications and systems” for general water services, “Simulation and experimental investigation of flow field and performance” including unsteady flows, instabilities, cavitation and verification using testing with measurement devices, “Mechanical systems” including seals, bearings and rotor dynamics analysis, and “Operation, monitoring and controls”.

Pumped and Energy Storage

This session focuses on the following topics: “Flexible systems and operation”, “Technical problems”, “Integration of pumped storage power plants in the global grid”, “Governance and regulation”, “Stability of dikes and dams subjected to pump/turbine operating conditions”, “Coastal and maritime installations”.

Pumps Working As Turbines (PAT)

The idea of using the standard pumps as hydraulic turbines especially for industrial recovery applications has been known for many years. On the other hand, substituting a conventional turbine by a standard pump for hydroelectric power generation is not yet well accepted and there are considerable debates on this subject. The main object of this session is to discuss technical aspects and practical challenges of using pumps as turbines. Topic areas covered by this session include the followings: measurement and numerical prediction of PAT hydraulic and mechanical characteristics (e.g. radial and axial trusts), optimization of PAT, PAT selection and economic concerns. Contributions for both radial and axial machines are welcome.     

Sustainable Hydropower

This session welcomes presentations covering sustainable development and challenges in the hydropower projects especially on (but not limited to) “Small hydropower”, “Decentralized development”, “Environmentally-friendly development”, “Operation and Maintenance”, “Load flexibility”, “Energy independence” and “Optimizes power supply”.

Ocean Hydro Machinery

Oceans cover more than 70% of the earth’s surface, making them the enormous source of energy. The area of ocean hydro energy includes wave energy, tidal energy, and marine current energy. This session focuses on the ocean hydro machinery which are mainly used to convert the ocean hydro energy into the mechanical energy for electricity production.

Hydraulic Systems

This session deals with “Dynamic behavior”, “Valves and gates”, “Water supply systems, “Penstock design and modernization” and “Free surface flows”.

Cavitation and Multiphase Flow

This session aims at gathering, exchanging and sharing information from researchers and engineers about experimental and numerical basic research of cavitation and multiphase flow. It is also welcome to propose new models, numerical methods, measuring techniques and the modifications for cavitation and multiphase flow.

Computational and Experimental Technique

Presentations about advanced techniques of experiment and analysis are welcomed in this session, such as optical approach for visualization, multipoint pressure measurement, advanced turbulence models or numerical scheme, transient analysis, etc.

General Topics

Presentations on the topics other than the above are welcomed in this session.
