Analytical modeling of turbine wakes in yawed conditions (2016)
Presentation / Conference Contribution
Bastankhah, M., & Porte-Agel, F. (2016, April). Analytical modeling of turbine wakes in yawed conditions. Poster presented at European Geosciences Union (EGU), Vienna, Austria

Increasing wind energy production has become a unanimous plan for virtually all the developed countries. In addition to constructing new wind farms, this goal can be achieved by making wind farms more efficient. Control strategies in wind farms, such...

A wind-tunnel investigation of wind-turbine wakes in yawed conditions (2015)
Presentation / Conference Contribution
Bastankhah, M., & Porté-Agel, F. A wind-tunnel investigation of wind-turbine wakes in yawed conditions. Presented at Wake Conference 2015, Visby, Sweden

Wind-tunnel experiments were performed to study the performance of a model wind turbine and its wake characteristics in a boundary layer under different operating conditions, including different yaw angles and tip speed ratios. High-resolution partic... Read More about A wind-tunnel investigation of wind-turbine wakes in yawed conditions.

A wind-tunnel investigation of wind-turbine wakes in differentyawed and loaded conditions (2015)
Presentation / Conference Contribution
Bastankhah, M., & Porte-Agel, F. (2015, April). A wind-tunnel investigation of wind-turbine wakes in differentyawed and loaded conditions. Paper presented at European Geosciences Union (EGU), Vienna, Austria

Wind-turbine wakes have negative effects on wind-farm performance. They are associated with: (a) the velocity deficit, which reduces the generated power of downwind turbines; and (b) the turbulence level, which increases the fatigue loads on downwind...

A new analytical model for wind turbine wakes (2014)
Presentation / Conference Contribution
Bastankhah, M., & Porte-Agel, F. (2014, December). A new analytical model for wind turbine wakes. Presented at International Conference on Aerodynamics of Offshore Wind Energy Systems and Wakes (ICOWES 2013), Lyngby, Denmark

Optimization of wind farm performancebased on yaw angle control (2014)
Presentation / Conference Contribution
Bastankhah, M., Dios Romero, I., & Porte-Agel, F. (2014, June). Optimization of wind farm performancebased on yaw angle control. Paper presented at 21st Symposium on Boundary Layers and Turbulence (BLT), Leeds, UK

Inside wind farms, the wakes of upwind turbines result in a significant reduction in power production. Yawing upwind turbines can be used to deflect the wakes away from turbines. Even though this reduces the power production of upwind turbines, it ca... Read More about Optimization of wind farm performancebased on yaw angle control.

A new analytical model for wind-turbine wakes (2014)
Journal Article
Bastankhah, M., & Porté-Agel, F. (2014). A new analytical model for wind-turbine wakes. Renewable Energy, 70, 116-123. https://doi.org/10.1016/j.renene.2014.01.002

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 de fi... Read More about A new analytical model for wind-turbine wakes.
