project
unitte supervision: niels troldborg abstract: lidars (
wind
speed measuring lasers) will change the way
wind
turbine
s sense the
wind
. instead of measuring far away from the
turbine
, they will measure within one rotor diameter of the
turbine
. this will enhance the correlation between the measured
wind
field and the one ultimately interacting with the
turbine
. it will lower the uncertainty in power curve assess- ment and allow better individual as well as communal
turbine
control. our inflow models are essential to these measurements close to the
turbine
rotor, as they will offset the mea- surement uncertainty from rotor effects. we use a multi-fidelity modelling approach in com- bination with extensive validation through field measurements. we validated of our high fideli- ty model and have derived a simple engineering model, which can be used for commercial pur- poses. furthermore, our findings might chan- nel into future iec standards on power curve assessment. name: jeppe bjørn jørgensen nationality: danish
project
title: adhesive joints in
wind
turbine
blades supervision: bent fruergaard sørensen abstract: the overall business objective of the
project
is to reduce the cost of energy by enabling manu- facturing of longer and more cost efficient
wind
turbine
blades. more specifically, this
project
will develop and improve analysis tools for ad- hesive joints in
wind
turbine
blades. this will enable the industry to design closer to the ac- tual structural limits. the main research objective is, based on frac- ture mechanics, to develop a generic analytical model which can predict the crack initiation and propagation of both the transverse and longi- tudinal cracks. the state of the art theory will be used together with modern experimental methods to generate generic models, which can be applicable on the family of joints. it will be beneficial if a single generic model can be ap- plicable to all members of the joint family. the mathematical models and analytical methods should be integrated into design rules, which are suitable for improving the joint design for large
wind
turbine
blades. the generic model of the joints must be developed using more detailed (e.g. cohesive zone) models, which are not yet available. name: kasper sandal nationality: norwegian
project
title: design optimisation of jacket structures for mass production supervision: jesper mathias stolpe abstract: offshore
wind
turbine
s are mounted on costly bottom-fixed support structures such as monopiles and jackets. design optimization of offshore
wind
turbine
sup- port structures is a complex engineering task. the newly funded danish strategic research
project
abyss at dtu
wind
ener- gu develops novel mathematical models, reliable numerical optimization techniques and software for optimal structural design of cost effective bottom-fixed offshore
wind
turbine
support structures for all rel- evant water depths including deep waters in excess of 50m. the particular responsi- bility of my phd
project
is to include mass manufacturing considerations in the opti- mization process.
