5.04.4239 - Wind Physics Students` Laboratory- Wind Turbine Rotor in Turbulent Inflow
- Dr. Michael Hölling
- Thomas Messmer
Dienstag: 08:00 - 11:45, wöchentlich (ab 02.04.2024)
The “Wind Physics Student's Lab" aims to foster the learning process by own research activities of the students in wind physics and additionally to build up skills for scientific and experimental work and scientific writing. Therefore, this course is also intended as preparation for the master thesis.
The course is organized as seminar with integrated work in the laboratory. The students will investigate an individual, self-formulated research question and will be guided by the supervisors through the research-based learning process. The work in groups and discussion of solutions aims to improve skills in team working.
In order to introduce the students to current wind energy research, the course is offered in different versions. These versions represent the work of different research groups at ForWind -University Oldenburg. The seminars will be offered in subsequent semesters or in parallel.
The seminar “Wind turbine rotor in turbulent inflow" is connected to the scientific work of the research group Turbulence, Wind Energy and Stochastics (TWIST).
In this seminar, turbulent wind fields and their effects on wind turbines will be investigated. Students learn to measure wind flows in high resolutions and how turbulence can be described, investigated and evaluated for different purposes. The students gain a deep understanding of the phenomenon of turbulence. They perform own experiments in a wind tunnel with an active turbulence grid. They learn to establish their own research questions and are encouraged to develop own methods.
The seminar consists of three main phases:
1st phase: Preparational learning
• building up basic competences
• introduction to current research
• practical measurements of flows with different sensors in the wind tunnel
• evaluation methods of data of turbulent wind flows
2nd phase: Research-based learning
• defining own research questions
• defining an experimental strategy
• planning the experiment
• set-up, execution, data acquisition and decommissioning of experiments
3rd phase: Evaluation and documentation
• evaluating the experiments
• documentation with a short report (paper)
• presentation.

Lecturer from German Aerospace Center (DLR) - Institute of Networked Energy Systems - Department Energy Analysis - Team Energy Meteorology:
The lecture addresses applications of solar energy meteorology. As a basis, most important physical laws for solar energy meteorology as well as models for solar resource assessment and forecasting are introduced. A special emphasis will be on evaluation concepts and applications.
• requirements for solar resource data from different applications
• models and measurement devices for solar resource assessment and forecasting
• benefits and drawbacks of different models
• methods to assess the quality of solar resource data
The lectures are combined with practical excercises in data handling, analysis and quality control of meteorological and solar radiation data. The exercises are based on Python programming language. Therefore basic skills of the programming language are required.
The course examination is done in project work and a short presentation of results in the last lecture of the course. The project work is strongly linked to daily applications in solar energy meteorology and based on research data from DLR institute.
