Special Issue Information

Dear Colleagues,

Hydropower is a major source of renewable energy (RE). However, there is significant concern about the environmental impact of large hydro plants working with large volumes of water stored in artificial basins. Thus, at present, running water mini hydro plants are the best RE producer with the highest power density and lowest environmental impact.

Mini hydro turbines have a number of advantages, for example, they meet the requirements of a distributed power energy system, they have a production variability lower than other RE producers and, when installed online within transport and distribution water pipes, they can provide two different and complementary functions: energy production and hydraulic regulation of discharge or pressure.

This new opportunity for hydropower production requires critical changes in turbine design, which have traditionally been designed for almost constant discharge and head jump values. Moreover, due to the low nominal power of the turbines, it is necessary to consider complementary machinery in order to obtain a net benefit from the installed device.

This Special Issue aims to provide an overview of the most recent advances in the field of hydraulic turbines and hydro plant design and management.

Potential topics will include, but are not limited to:

  • The design of new hydraulic turbines for running water plants;
  • The design of new electric systems for electricity generation in running water hydro plants;
  • Mechanic design of new hydraulic turbines;
  • Cyber security in hydro plants;
  • Mini hydro plants and smart grids;
  • Cost/benefit analysis of mini hydro plants;
  • Advances in the design of high-power hydraulic turbines.

In the last few decades, hydropower production has been moving toward a new paradigm of low and diffused power density production of energy with small and mini-hydro plants, which usually do not require significant water storage. In the case of nominal power lower than 20 kW and ultra-low head H (H < 5 m), Archimedes screw or Kaplan type turbines are usually chosen due to their efficiency, which is higher than 0.85. A new cross-flow type turbine called Ultra-low Power Recovery System (UL-PRS) is proposed and its geometry and design criteria are validated in a wide range of operating conditions through 2D numerical analysis computed using the ANSYS Fluent solver. The new proposed solution is much simpler than the previously mentioned competitors; its outlet flow has a horizontal direction and attains similar efficiency. The costs of the UL-PRS turbine are compared with the costs of one Kaplan and one cross-flow turbine (CFT) in the case study of the main water treatment plant of the city of Palermo in Italy. In this case, the UL-PRS efficiency is estimated using a URANS 3D numerical analysis computed with the CFX solver. Full article
