Along with the increasing industrialization of contries and population growth, the global. With the thougth of overcoming climate change and renducing greenhouse gas emissions in the atmosphere, interest in alternative sloar, wind, water, geothermal, tidal and ocean wave energy has significantly increased. Hydropower is one of the most used inexhaustible sources of energy on a global scale. The efficiency of water turbines can be increased by optimizing the blade cascade and the casing. For this purpose, research is conducted on specialized laboratory benches. The purpose is to determine the influencing parameters which affecting the nature of the power and cavitaion curves This paper presents the results of numerical and laboratoty studies of axial hydrokinetic turbines. A detailed analysis of the influence of the geometric parameters of the blades on the operating curves is made. A mathematica model for synthesis of the blade cascade is derived. An assessment of water energy soures has been made and sites of high energy potential have been pointed. The present material can be used for development of a methodology for calculation of efficient axial hydrokinetic turbines.

“…The main ways to increase the power extracted at the same flow rate are to use intubations with different shapes and angles of flare, use rotor blades adapted to a particular flow, and increase the rotor's diameter as much as possible. For the estimation of the power of a real-scale hydrokinetic turbine, experimental models can be used, on a progressive scale, for which the curves of the power coefficient [6,7] are drawn. An example of a hydrokinetic turbine is studied in this paper, developed in an experimental research project (PED478 / 2020 -Hyper).…”

The renewable energy policy strongly encourages the use of all renewable sources of energy. The authors started to develop a new hydrokinetic turbine to be implemented in small rivers or water channels with a low investment cost. This paper presents velocity map distribution around a hydrokinetic turbine prototype. Experimental measurements were performed using a Particle Image Velocimetry system in a water channel, while the water velocity and turbine rotation speed were variated. Images are presented in the same rotor position and the rotational flow is captured downstream of the blades, at different turbine operating modes. This paper is part of a larger study on developing an innovative axial hydrokinetic turbine. The resulting velocity distribution will be used to validate the numerical model.

The present paper is part of a larger project whose purpose is to develop a new hydrokinetic turbine-generator assembly, suitable for very low head water courses. It presents the experimental results of a turbine–generator physical model, installed on the tailrace of Mihailesti Hydropower Plant. In order to carry out the measurements, a floating structure and an anchoring system was installed on the power plant tailrace. This system also allowed the translation of the assembly between the two shores. A first set of measurements followed the water velocity and depth in the channel at various load values of the hydropower plant units, in order to determine the proper conditions for testing the model. The turbine gives the possibility of blades adjustment at three different angles, 0, 9 and 14 degrees respectively. Therefore, a set of measurements has been performed for each position of the blades. The measured parameters were the electric parameters of the generator such as voltage, current and the power variation with rotation speed. For the blades adjustment of 9 degrees and 1.76 m/s water velocity, the generator reached its maximum power of 500 W. The results retrieved will be used for the optimization and design of a new enlarged scale turbine–generator assembly. They will also be used as input data for the numerical modeling of the generator. Also, the exact knowledge of the channel geometry and flow parameters is valuable in studies preceding testing a prototype in the site.
