Simulating Collisions for Hydrokinetic Turbines

Abstract: Evaluations of potential blade-strike on an axial-flow marine hydrokinetic (MHK) turbine were conducted using a method that integrates the following components into a computational fluid dynamics (CFD) model: (i) advanced eddy-resolving flow simulations, (ii) inflow turbulence based on field data, (iii) moving turbine blades in a transient flow, and (iv) Lagrangian particles to represent fish. The sensitivity of blade-strike probability to the following conditions was also evaluated: (i) turbulent environment,… Show more

“…This turbine was designed using blade element momentum (BEM) theory, and the profiles of the lifting surfaces were determined using the subsonic airfoil design tool 'XFOIL' [15]. The development of this device has been a multi-institutional effort involving design at Sandia National Laboratories [16], blade element momentum modeling at UC Davis [15], laboratory testing at Pennsylvania State University [17] and hydraulic and biological performance assessments at the Pacific Northwest National Laboratory [18,19].…”

“…The seabed and turbine structure were modeled as no-slip solid walls. Further details on the CFD modeling methods used are reported by Richmond and Romero-Gomez [23,24]. The resulting incident and near wake flow velocities, normalized by the nominal flow speed of 2.0 m/s are presented in Fig.…”
