„It is a great pleasure for me to be involved in this forward-looking and innovative research project CRC1463. The new subproject A07, in which I am involved, is investigating the effects of mega offshore wind farm structures on fluid flows in the atmospheric boundary layer and in the ocean. We will look at meteorological and oceanographic phenomena that become important for particularly large wind farm clusters due to their dimensions. As part of this subproject, I will carry out numerical flow simulations using state-of-the-art turbulence-resolving Large Eddy Simulations (LES).
I already applied the model last year as part of my master's thesis in meteorology. In my thesis, I investigated the effects of surface obstacles, such as buildings and complex terrain, on the loads and energy yield of a wind farm. As an example of a complex terrain, I chose the industrial site ‘Hamburg Harbour’. I am therefore very happy to continue working in the field of wind energy research and to contribute my meteorological expertise to the CRC.“ (Yasmin Ahlert)

“The increasing size of wind turbines requires a better understanding of the interactions between wind turbines and the atmosphere. In particular, “challenging”, coherent atmospheric conditions can cause large loads on the turbines.
Within the CRC subproject A07 we will investigate these special atmospheric conditions and their interaction with wind turbines. Numerical data and measurements at an offshore wind farm and an onshore site will be used for this purpose. Both LiDAR (light detection and ranging) measurements and SCADA data will be explored. Methods for the reconstruction of wind fields from radial wind speeds using LiDAR measurements are being further developed and validated in order to subsequently use them for the detection of coherent atmospheric structures.
During my Master's thesis, I worked with synthetic data and measurements for the estimation of the wind resource and was subsequently able to gain initial experience with lidar technology and its measurement principles. The CRC 1463 - Phase 2 now allows me to dive further into the technology and investigate coherent atmospheric structures.” (Paul Meyer)
