Overview
The Wind Energy Division has an open PhD position concerning the flow of air over complex forested terrain. The PhD student will work within the research center for computational wind turbine aerodynamics and atmospheric turbulence, which is funded by the Danish Strategic Research Council running from 2010 to 2015.
Project description
The correct placement of wind turbines is crucial for maximizing their output. Siting of turbines in or near forests is becoming increasingly common, despite the fact that forested areas are not optimal sites, due to high shear and turbulence levels in the wind field. Accurate predictions of forest flow are therefore of great importance for the wind energy community. Forested areas are generally characterized by large-scale heterogeneities, either due to the natural variation in the landscape such as lakes and mires or due to clearings in the managed forests. These heterogeneities add to the complexity of the flow. For forested hilly terrain, the prediction of the separation of the flow above and below the canopy may be critical for assessing the flow field around the hill correctly.
Since several years, the Wind Energy Division has run/is running field experiments in or near forested areas using both traditionally instrumented masts and ground-based remote sensing laser instruments (lidars). Researchers at the Wind Energy Division were the first to employ such lidars in scientific experiments for wind energy. You will be involved in:
- analyzing datasets from these experiments
- running state-of-the-art cluster-based advanced flow modeling of the sites for comparison with the experimental data
- improving the forest-parameterization in the model
You will work in a team of researchers, who all focus on canopy flow, and you are also expected to cooperate with other PhD students in the Research Center. You are expected to visit measurement sites to get a good understanding of the limitation of measurement-model comparisons.
Qualifications
Candidates should have a master's degree in physics, meteorology, engineering or mathematics or a similar degree with an academic level equivalent to the master's degree. Experience with fluid dynamics or boundary layer meteorology, as well as good communication skills are considered advantageous for obtaining the position.
Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.
Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.The place of work will be Risø DTU in Roskilde.
Further information
You are welcome to contact Senior Researcher Ebba Dellwik, ebde@risoe.dtu.dk, +45 4677 5032 or Senior Researcher Andreas Bechmann, andh@risoe.dtu.dk, +45 4677 5967.
Application
We must have your online application by 15 february 2011. Please open the link "apply for this job online", fill in the application form and attach the following documents;
a) A letter motivating the application (cover letter)
b) Curriculum vitae
c) Grade transcripts and BSc/MSc diploma
d) Conversion of grade averages to Danish grades (see guidelines and excel spreadsheet for the conversion here).
Candidates may apply prior to obtaining their master's degree, but cannot begin before having received it.
All interested candidates irrespective of age, gender, race, inability, religion or ethnic background are encouraged to apply.
