In recent years, the cross-flow hydrokinetic turbines (HKTs) have been researched intensively owing to their key characteristics such as independency of flow direction and simple design. The Savonius turbine, being a drag-based device is known to have good starting performance. On the other hand, the lift-based Darrieus turbine, in several studies, has demonstrated reasonable efficiency over a wide range of flow velocities. To capitalize on the respective advantages, both the devices can be integrated together on the same axis thus forming a combined/hybrid turbine. In this paper, the authors have collected and analyzed published studies that investigate the performance of such hybrid Savonius-Darrieus designs with respect to hydrokinetic applications. Hardly a review study exists hitherto which solely discusses the studies for hybrid turbine that have been conducted using water as the operating fluid. Therefore, the primary aim of this paper is to establish a distinct research background for the hybrid turbine exclusively in terms of hydrokinetic applications. In addition to summarizing the existing literature, the present study also highlights the key gaps that will further enable the concerned researchers to explore the uninvestigated aspects within the domain of hybrid HKTs.

A Comparative Study on the Performance of a Horizontal Axis Ocean Current Turbine Considering Deflector and Operating Depths Maldar, Nauman Riyaz; Ng, Cheng Yee; Ean, Lee Woen; Oğuz, Elif; Fitriadhy, Ahmad; Kang, Hooi Siang (MDPI AG, 2020-04-01) Several different designs and prototypes of ocean current turbines have been tested over recent years. For every design test, emphasis is given to achieving an optimum power output from the flow. In this study, the performance of a Horizontal Axis Ocean Current Turbine (HAOCT) has been investigated using three-dimensional Computational Fluid Dynamics (CFD) simulations for three cases, namely, (1) a turbine without a deflector, (2) a turbine with a deflector, and (3) a turbine with a deflector operating at a...
A Numerical Study on the Behavior of Offshore Suction Bucket Foundations under Cyclic Lateral Loading Alp, Yilmaz S.; Ercan, Tasan H. (2020-01-01) Offshore wind turbines are exposed to high cyclic lateral loads induced by wind and waves which play a special role in the design of foundations. It's essential to clarify the bucket behavior under cyclic lateral loading to fulfil the design requirements of these foundations in both ultimate and serviceability limit states. In this study the behavior of monopods embedded in saturated sandy soil subjected to cyclic lateral loads were investigated using a sophisticated finite element model. The accumulation o...
A Numerical Study on the Behaviour of Suction Bucket Foundations for Offshore Wind Turbines under Cyclic Loading Yılmaz, Seyit Alp; Bakır, Bahadır Sadık; Taşan, Hacı Ercan; Department of Civil Engineering (2021-5-24) Suction bucket foundations simply consist of a cylinder skirt and a top plate, usually made of steel and installed by the assist of suction are a relatively new and economically favorable solution for offshore wind turbines which are exposed to high lateral loads from winds and waves both of which have cyclic characteristic. Understanding the behaviour under the effect of complex cyclic load environment is essential to assess the design requirements of bucket foundations. Deformations and pore pressures may...
Experimental Modal Analysis of Geometrically Nonlinear Structures by Using Response-Controlled Stepped-Sine Testing Karaağaçlı, Taylan; Özgüven, Hasan Nevzat (2022-01-01) The everlasting competition in the industry to achieve higher performance in aircraft, satellites, and wind turbines encourages lightweight design more than ever, which eventually gives birth to more flexible engineering structures exhibiting large deformations in operational conditions. Accordingly, continuously distributed geometrical nonlinearity resulting from large deformations is currently an important design consideration. Being guided with this motivation, this paper investigates the performance of ...
Comparison of Various Spring Analogy Mesh Deformation Techniques in 2 D Airfoil Design Optimization Yang, Yosheph; Özgen, Serkan (null, 2015-06-29) During the last few decades, CFD (Computational Fluid Dynamics) has developed greatly and has become a more reliable tool for the conceptual phase of aircraft design. This tool is generally combined with an optimization algorithm. In the optimization phase, the need for regenerating the computational mesh might become cumbersome, especially when the number of design parameters is high. For this reason, several mesh generation and deformation techniques have been developed in the past decades. One of the mos...
