Heat Transfer Characteristics of High Crossflow Impingement Channels: Effect of Number of Holes

Peter Ott, Alexandros Terzis, Santiago Llucià

In modern turbine airfoils, narrow impingement cooling channels can be formed in a double-wall configuration. In these wall-integrated cooling cavities, the generated crossflow is one of the most important design factors, and hence, the number of impingeme ...

Prediction of the hub vortex instability in a wind turbine wake: stability analysis with eddy-viscosity models calibrated on wind tunnel data

Fernando Porté Agel, François Gallaire, Giacomo Valerio Iungo, Francesco Viola

The evolution and downwind recovery of wind turbine wakes are crucial factors for the evaluation of waketo-wake interactions within a wind farm and, in turn, for the prediction of wind power harvesting. Wind turbine wakes are affected by the design of wind ...

A New Analytical Model For Wind-Turbine Wakes

Fernando Porté Agel, Majid Bastankhah

A new analytical wake model is proposed and validated to predict the wind velocity distribution downwind of a wind turbine. The model is derived by applying conservation of mass and momentum and assuming a Gaussian distribution for the velocity deficit in ...

Optimization of an Airborne Wind Energy System Using Constrained Gaussian Processes

Colin Neil Jones, Ioannis Lymperopoulos, Sanket Sanjay Diwale

Wind resources tend to be significantly stronger and more consistent with increasing altitude. This effect creates a potential for power generation that can be reaped by an Airborne Wind Energy system positioned at elevations exceeding the height of conven ...

Large Eddy Simulation of Vertical Axis Wind Turbine Wakes

Fernando Porté Agel, Sina Shamsoddin

In this study, large eddy simulation (LES) is combined with a turbine model to investigate the wake behind a vertical-axis wind turbine (VAWT) in a three-dimensional turbulent flow. Two methods are used to model the subgrid-scale (SGS) stresses: (a) the Sm ...

Influence of the Hydraulic System Layout on the Stability of a Mixed Islanded Power Network

François Avellan, Christophe Nicolet, Christian Landry, Stefano Giacomini

Numerical simulation and stability analysis of an islanded power network comprising 40 MW of hydropower, 20 MW of wind power and 60 MW of gas-fired power plant are investigated. First, the modeling of each power plant is fully described. The wind farm is m ...
