MEK4460 – LES in marine hydrodynamics and offshore wind power
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.
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.
Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.
If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.
Recommended previous knowledge
MEK3230 – Fluid Mechanics, MEK3220 – Continuum Mechanics (discontinued)/MEK4220 – Continuum Mechanics (discontinued), MEK4330 – Turbulence theory and modeling/MEK9330 – Turbulence theory and modeling. It is an advantage to have taken MEK4420 – Marine Hydrodynamics/MEK9420 – Marine Hydrodynamics.
5 credits overlap with MEK9460 – LES in marine hydrodynamics and offshore wind power
*The information about overlaps for discontinued courses may not be complete. If you have questions, please contact the Department.
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.
The grade is based on the written project, with an oral presentation at either DTU or UiO.
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.
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.
The course is subject to continuous evaluation. At regular intervals we also ask students to participate in a more comprehensive evaluation.
