“…The drag coefficient is higher for the concave surface than for the convex side in Savonius rotor. Therefore, more drag force is experienced by the advancing blade (with concave side) than by the returning blade . Drag‐based configuration converts 20% less energy than does lift‐based configuration .…”

Summary The drastic change in climatic conditions has led to shift towards the review of sustainable strategies in the renewable energy sector. Hydrokinetic technology has various benefits over the conventional methods, which can be helpful in achieving the desired sustainable development. In the present study, an outline for the conversion of hydrokinetic energy along with its challenges has been discussed. The study comprises of three steps involving collection of properties required for site characterization followed by selection of the suitable hydrokinetic device as per the site characteristics and the determination of impact on the flow condition due to device installation. The characteristics of the site govern the selection of the device, its mooring arrangements, and augmentation. The arrangement of devices as a single unit or in an array will have an impact on the flow conditions. The altered flow condition will in turn affect and change the characteristics of the site. This three‐step process is interlinked and will have a cumulative impact on the environment. The influence of environmental impact and cost of energy, which are the two major factors for the success of this technology, are also discussed. Further, various challenges faced by hydrokinetic technology in its development are explored. It is concluded that only the optimization of a hydrokinetic device for its efficiency improvement will not be fruitful until its impact on flow condition is considered for optimization.

“…In hilly remote areas, lot of streams are available with gravity powered flowing water. These flowing streams can be used as the prime source of energy generation by capturing the kinetic energy of water . The kinetic energy of water can be tapped with the help of various hydrokinetic systems known as hydrokinetic turbines.…”

Summary Increased demand of energy leads to exploration of new sources of energy. In the last few years, hydrokinetic energy technology emerged as an important area in the field of renewable energy generation. Various hydrokinetic turbines have been studied and used to harness the hydrokinetic potential. Among all hydrokinetic turbine technology, cross‐flow hydrokinetic turbine is considered as the most suitable approach for the riverine system. There are various configurations of cross‐flow hydrokinetic turbine exist for hydrokinetic energy extraction. A number of numerical and experimental studies were carried out on the performance enhancement and design optimization of different configurations under variable operating conditions. Under the present paper, review of different rotor for the configurations of the cross‐flow hydrokinetic turbines are discussed. The paper will be useful to understand the cross‐flow hydrokinetic technology in order to explore the methods for selection, performance enhancement, and design optimization of cross‐flow hydrokinetic turbines.

The underwater mobile monitoring platform that utilizes marine animals as carriers provides a new solution to address the issues of short endurance, high costs, and bulky size associated with traditional underwater mobile monitoring platforms. Based on most marine animals that have the behavioral habit of long‐duration swimming, a micro hydrokinetic energy harvesting system is proposed. This system applies a miniature vertical‐axis water turbine as its energy conversion component. The hydrokinetic energy is derived from the relative movement between marine animals and the surrounding seawater. A conceptual design of a novel underwater mobile monitoring platform is presented. A finite element model of the external‐rotor permanent magnet synchronous generator is established to comprehensively evaluate the performance of the generator. Numerical simulation is utilized to conduct a comparative analysis of different diversion channel designs. Preliminary water tank experiments show that the designed micro energy harvester can effectively capture the hydrokinetic energy generated by water flow movement. The startup flow rate of the harvester is around 0.16 m s−1. The output power increases with the increase in water flow velocity, reaching a maximum value of ≈57 mW within the range of water flow rate of about 0.2–0.5 m s−1.
