Designing multi-rotor tidal turbine fences

Navier-Stokes CFD Analysis of a Tidal Turbine Rotor in Steady and Planar Oscillatory Flow

Initial results of an ongoing Navier-Stokes Computational Fluid Dynamics study of horizontal axis tidal current turbine hydrodynamics are presented. Part of the underlying motivation is assessing the effects of the Reynolds number on turbine performance and loads in steady and unsteady flow regimes. The study aims at a) providing initial verification and validation of Navier-Stokes CFD for stea...

Harnessing Tidal Energy Using Vertical Axis Tidal Turbine

An overview of the current design practices in the field of Renewable Energy (RE) is presented; also paper delineates the background to the development of unique and novel techniques for power generation using the kinetic energy of tidal streams and other marine currents. Also this study focuses only on vertical axis tidal turbine. Tidal stream devices have been developed as an alternative meth...

Design and Optimization of Tidal turbine Airfoil

Modelling a Tidal Turbine in Unsteady Flow

A brief review of the literature is provided on the characteristics of marine currents and the approaches used for simulating tidal turbines. The feasibility of using CFD models to simulate time-dependent turbulent flow around a tidal turbine is then explored. Two different approaches for specifying the structure of the turbulent inflow conditions in CFD models are compared: the von Kármán spec...

A complete algorithm for designing passive fences to orient parts

Peshkin and Sanderson showed that parts can be aligned as they move on a conveyor belt against a pass ive sequence of fences In this paper we describe the rst complete algorithm to design such sequences for a given convex polygonal part The algorithm is com plete in the sense that it is guaranteed to nd a design if one exists and to terminate with a negative report oth erwise Based on an exact ...
