MEK9460 – LES in marine hydrodynamics and offshore wind power
Course description
Course content
LES with dynamic Smagorinsky model and flow separation, wave analysis of a fixed or floating vertical cylinder by nonlinear potential theory in long wave regime, Morison's equation, wind turbine and wake aerodynamics, blade-element/momentum theory, rotor loads and atmospheric boundary layer profiles.
Learning outcome
Introduction to Large Eddy Simulation, filtering techniques, dynamic Smagorinsky modelling. Morison's equation. Flow separation effects calculated by LES. Nonlinear long-wave analysis of moored and fixed cylinders. Fundamental and super harmonic forces and responses. Response characteristics of the HYWIND offshore wind test turbine (when available). Wind turbine aerodynamics. Blade-element/momentum theory. Wake aerodynamics. Distributed momentum sources in LES to represent rotor loads. The actuator line technique. Synthetic turbulence and atmospheric boundary layer profiles using distributed momentum sources. Stability of wakes.
Admission
PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.
If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.
PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.
Prerequisites
Recommended previous knowledge
MEK3230 – Fluid Mechanics, MEK3220 – Continuum Mechanics (discontinued), MEK4330 – Turbulence theory and modeling (discontinued)/MEK9330 – Turbulence theory and modeling (discontinued). It is an advantage to have taken MEK4420 – Marine Hydrodynamics/MEK9420 – Marine Hydrodynamics.
Overlapping courses
5 credits overlap with MEK4460 – LES in marine hydrodynamics and offshore wind power (discontinued)
* The information about overlaps for discontinued courses may not be complete. If you have questions, please contact the Department.
Teaching
The course is given intensively over a short period.
The teaching period has three parts:
Part 1: 3 full days of lectures in Oslo.
Part 2: 2-3 weeks of lecture break with the students preparing a larger written project.
Part 3: 3 full days of lectures in Lyngby.
Upon the attendance of three or fewer students, the lecturer may, in conjunction with the Head of Teaching, change the course to self-study with supervision.
Examination
The grade is based on the written project, with an oral presentation at either DTU or UiO.
PhD candidates must deliver one extra obligatory exercise, which must be at an advanced level within the curriculum of the course, or be a theoretical extension of the curriculum of the course, and should preferably relate the contents of the course to newer research literature. You may be required to give an oral presentation and/or deliver a written report. The exercise must be passed to be allowed to take the ?nal exam.
Examination support material
No examination support material is allowed.
Language of examination
Subjects taught in English will only offer the exam paper in English.
You may write your examination paper in Norwegian, Swedish, Danish or English.
Grading scale
Grades are awarded on a pass/fail scale. Read more about the grading system.
Explanations and appeals
Resit an examination
Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester.
Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.
Withdrawal from an examination
It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.
Special examination arrangements
Application form, deadline and requirements for special examination arrangements.
Evaluation
The course is subject to continuous evaluation. At regular intervals we also ask students to participate in a more comprehensive evaluation.
