A semi-analytical model for velocity profile at wind turbine wake using blade element momentum
The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. Th...

متن کاملComputational Fluid Dynamics (CFD) Mesh Independency Study of A Straight Blade Horizontal Axis Tidal Turbine
This paper numerically investigates a 3D mesh independency study of a straight blade horizontal axis tidal turbine modelled using Computational Fluid Dynamics (CFD). The solution was produced by employing two turbulence models, the standard k-ε model and Shear Stress Transport (SST) in ANSYS CFX. Three parameters were investigated: mesh resolution, turbulence model, and power coefficient in the...

متن کاملPerformance Prediction of a Free Stream Tidal Turbine with Composite Bend-Twist Coupled Blades
Free stream tidal turbines are a source of growing interest in the marine renewable energy field. Some designs that use an actuated mechanism to control individual blade pitch, as the tidal current varies and even during a revolutionary cycle, face the challenge of ensuring high reliability under the loads imposed on the device in the harsh sub sea environment. Adaptive materials have been used...
