Progress and achievements until May 2022

The kick-off meeting of Task 47 Turbinia  was held on-line in three sessions of 2.5 hours on April 6, 8 and 9 2021. At this meeting the planning of activities was refined and detailed for year 2021 after which the project got into full swing. Several follow-up meetings took place on-line and on May 30, the day before the Science of Making Torque conference, a first hybrid (personal/on-line) meeting will be held at TNO Delft.

Within WP1  several countries started to define detailed aerodynamic measurement programs and several new aerodynamic measurement technologies are developed and applied, e.g. MEMS based pressure sensors, fibre optic pressure sensors and pressure belts. Some first data are collected already.

In order to share experiences on this specialized field of aerodynamic measurements, at the benefit of others use is made of  the WeDoWind collaboration and knowledge sharing platform developed by the Eastern Switzerland University of Applied Sciences (OST). With this platform it is possible to share knowledge, data and code on issues related to aerodynamic measurements and simulations. Thereto several “discussion challenges” have been defined which are considered relevant subjects for further discussions in Task 47. Examples of challenges are: How to find the angle of attack in aerodynamic field experiments, how to compare (turbulent) simulations and measurements, how to do standstill measurements etc. Moderated workshops are organized for each challenge. These workshops are recorded and documented in a structured way on the WeDoWind platform so that they can form reference material for future users.

Moreover a calculational case is defined around the DanAero experiment where the comparison is done on the basis of time series.  Thereto, it should be noted that a ‘conventional’ comparison on statistical properties depends heavily on the random seed which is needed for the turbulent wind field generation. A comparison based on time series basis turns out to be very challenging since the timing of results from lifting line codes, CFD codes and measurements all need to be synchronized. Some first steps are made where turbulent winds are generated and prescribed based on measurements at the meteorological mast. Generally the agreement between calculational results mutually is satisfactory but there are still issues to solve in order to reach a satisfactory agreement between calculations and measurements.

Within WP2 a first preparatory case  is defined for the IEA 15-MW Reference Wind Turbine which aims to check the correct aerodynamic and aero-elastic input so that trivial input errors are eliminated in the follow-up calculational rounds. Thereto, aerodynamic simulations are carried out under relatively simple conditions, with uniform steady inflow. The activities on the 15-MW Reference Wind Turbine are coordinated with IEA Task 37.

Task 47 Roadmap

The Task 47 begin date is January 1st 2021 after which it will run for 4 years until December 31st 2024. A detailed planning of the activities can be found under the tab Work Plan and Objectives.

For now the most important event is the kick-off meeting which will be held on-line in three sessions of 2.5 hours on April 6, 8 and 9 2021. At this meeting the planning of activities will be refined and detailed for the coming period.

The schedule of personal meeting is put on hold due to the Corona pandemic. If the situation improves personal meetings will be organised again. It is anticipated that they will be held on an annual basis, mostly in Europe in view of the fact that the majority of the participants is European but meetings in the US and China are anticipated too.
