Due to limitation of energy resources, a large body of research activities has been turned to investigate potential alternative avenues to supply energy. In this regard, the renewable sources, which can provide the sustainable and cleaner energy production, have increasingly become attractive. Hydropower has the highest proportion of the renewable energy sources. Availability and high efficiency are the undeniable advantages of the hydro potentials. In this paper, hydro-energy extraction from pipelines by a new designed vertical axis turbine is studied experimentally and numerically. The turbine scheme is inspired by the Savonius rotor turbine, which includes two semicircular blades that is built by the 3D printer and installed vertically in a 100 mm transparent pipe. A sloped block is used just before the turbine blades to concentrate the flow and enhance the efficiency. In experiments, flow rate ranges from 2.7 × 10−3 m3/s to 7.3 × 10−3 m3/s and pressure drop that occurs through the turbine is less than 10.5 kPa. Numerical results show an acceptable agreement with experiments and assure that numerical method is reliable. Following successful validation, numerical studies are expanded, in order to study more details on the new turbine performance. According to the numerical results, the characteristic curves of the new turbine are depicted and described. In numerical simulation, for different turbine rotational speeds, the flow rate and the pressure difference examined are up to 12 × 10−3 m3/s and 30 kPa, respectively. Using the obtained results, investigations and studies are performed to describe turbine behavior under the effects of changing the clearance and flow field conditions. Finally, cyclic variations of turbine flow rate, torque and minimum pressure on the turbine blade are described by velocities streamlines. This approach might preform design improving for such a turbine.

Low-head microhydro systems for energy production are becoming accepted because of oil crises and new advances in their design and efficiencies. As this is still a new area for development and experimentation, it is important to test and validate the optimal conditions and the hydrodynamic behaviour of such systems under different conditions. The aim of this paper is to present a turbine design validation practise, which researchers and equipment manufactures can use for the hydrodynamic behaviour analysis of new low-head turbines prior to production and application. Laboratory experimental tests and advanced CFD numerical analysis are described for the flow behaviour analysis of a new prototype microtubular propeller. Laboratory experimental results are presented and used for the evaluation of the turbine performance curves. Comparisons between experimental and CFD results are also presented. Finally, an assessment of the hydrodynamic behaviour is made for a scaled model application, using the theory of turbomachine similarity.

A procedure for the design of the runner of a pico hydraulic propeller turbine according to the specific conditions of water potential of the site of operation is presented based on a theoretical and technical analysis. For this purpose the main characteristics of the runner are determined and data such as the suction head, the rated flow, and the occurring forces are established during the design. Modern engineering tools such as Computational Fluid Dynamics (CFD) are utilized for predicting the flow and Computer Aided Engineering software (CAE) for the design verification. The Runner of the Propeller Turbines (RPT) designed can be a viable option for electricity generation innot interconnected zones (NIZ) of the national interconnected electric system in developing countries and can be manufacture locally.
