Turbulence Model Development for the Atmospheric Boundary Layer
Host Organisation

Project Description
The main objective of my PhD project is to further develop numerical and stochastic wind field models that consider the empirically observed presence of large-scale coherent structures and the accurate statistical significance of extreme wind gusts in the atmospheric boundary layer. A secondary goal is to analyze the relationship between the generated inflow wind fields and the wind turbine rotor loads and dynamics under various atmospheric conditions. This involves stochastic wind field reconstruction and modeling for a variety of atmospheric conditions, processing large amounts of wind field data by combining LiDAR measurements with meteorological information, possibly flow models and wind turbine load data, and identifying turbulence structures with high relevance for turbine loading through aeroelastic simulations.

Background
I am Rojin Shokri Khanghah, born in Tehran, Iran, in September 1997. I hold both a BSc (2019) and an MSc (2021) in Aerospace Engineering from Tehran Polytechnic. My passion for aerodynamics led me to focus on the aero-acoustic noise and turbulence properties in vertical-axis wind turbines for my master’s project. I investigated turbulence characteristics and the way they affect the aerodynamic noise. After obtaining my MSc, I joined the industry to gain more experience, working as an aero-engine test and evaluation designer, designing air turbulence reduction structures. At AptWind, I’d focus on the complex interaction between atmospheric turbulence and wind turbine loads, which I am really enthusiastic about. Outside the lab, I enjoy hiking and savoring good food!
​
At AptWind, I contribute to state-of-the-art research and creative solutions in wind turbine technology. Here, my love of aerodynamics and turbulence has found the ideal home. I'm especially interested in the complex technical challenges of modeling atmospheric boundary layer turbulence using mathematical and physical principles. There is still a lot to learn and explore in this field. Furthermore, the collaborative approach that links academia and industry excite me greatly. By working with accomplished professionals and well-known figures in the field, I will be able to contribute to the advancement of wind turbine technology.
