Numerical analysis of on the effects of Hydrokinetic turbine presence in flow structure of a compound open-channel
In the recent years, due to the hydropower plants environmental problems, hydrokinetic turbine usages has been increased. Using such turbines in rivers modify natural flow-field. In previous studies, impacts of turbine on the flow-field just only in rectangular open-channel is studied. In this work, the effects of hydrokinetic turbine in a straight compound channel has been numerically studied ...
متن کاملInteractions between turbulent open channel flow, power and the wake of an axial-flow marine turbine
I. Introduction Until recently, an understanding of the range of scales of turbulent flow and its dynamic interaction with the performance and wake characteristics of axial-flow marine hydrokinetic turbines was lacking. Advancing this area of knowledge within the field of marine and hydrokinetic energy research, development, and deployment will lead to more efficient turbine operations and redu...
متن کاملUS Department of Energy (DOE) National Lab Activities in Marine Hydrokinetics: Scaled Model Testing of DOE Reference Turbines
Our aim in this paper is to present a brief overview of the scaled hydrokinetic turbine model testing activities in the United States using test turbines specifically designed by the US Department of Energy for its Marine and Hydrokinetic Research and Development program. These test turbines include: (1) a three-bladed horizontal axis turbine (the Sandia turbine) that was designed to demonstrat...
متن کاملHYDROKAL: A module for in-stream hydrokinetic resource assessment
A new tool for hydrokinetic energy potential assessment in rivers—HYDROKAL, which stands for a ‘‘hydrokinetic calculator’’—is presented. This tool was developed in the Fortran 90 programming language as an external module for the CCHE2D application, an existing two-dimensional hydrodynamic numerical model developed at the National Center for Computational Hydroscience and Engineering, Universit...
متن کاملAn Evaluation of Blockage Corrections for a Helical Cross-Flow Turbine
The ability to accurately evaluate hydrokinetic turbine concepts at small-scale in experimental facilities is important for the development of new devices. Problems introduced by working at lab-scale include operation in a transitional Reynolds number regime and cross-sectional blockage. These factors are shown to influence performance characteristics of a helical cross-flow turbine tested over...
