Course content
Phenomenological and theoretical introduction to turbulence and the scales found within it. Reynolds' decomposition and Reynolds' averaging. Homogeneous turbulence. Turbulent shear flows: boundary layers, jets and wakes. Introduction to turbulence modelling: algebraic and transport models. Practice examples with turbulent flow data.
Learning outcome
Knowledge:
After completion of this course, the student will have knowledge on:
- Basic laws in fluid mechanics.
- Cartesian tensor notation.
- Dimensionless equations, Reynolds and Strouhal number, scales for length and time.
- Vorticity and elements of vortex dynamics.
- Characteristics of turbulence including the scales within it.
- Reynolds’ decomposition, Reynolds-averaged Navier-Stokes equations (RANS).
- Balance equations for the mean flow and the turbulent kinetic energy.
- Turbulence near solid surfaces. The mean velocity profile. Boundary layer equations.
- Free turbulent shear flows. Simplified momentum equations. Self-preservation.
- Turbulence modelling. Eddy viscosity, mixing-length, Reynolds stress models.
- Statistical description of turbulence: moments, correlations, spectra.
- The concepts of direct numerical simulation (DNS) and large-eddy simulation (LES).
Skills:
After completion of this course, the student will have skills on:
- Evaluation of turbulent flow situations.
- Use of self-preservation solutions for free shear flows (jets, wakes, etc).
- Choose a turbulence model for computational flow analysis (CFD).
- Evaluate and interpret experimental measurements.
General competence:
After completion of this course, the student will have general competence on:
- The theory of turbulence and the turbulent flow of liquids and gases (fluids).
- An understanding of turbulent flow cases.
Learning methods and activities
Lectures, written exercises, a project and a laboratory exercise. The lectures and course activities are in English. The exam will be given in English only. Students are free to choose Norwegian or English for written assessments.
Further on evaluation
The portfolio evaluation will consist of a lab report and problem exercises. For a re-take of an examination, the portfolio may be omitted if previously completed.
If there is a re-sit examination, the examination form may be changed from written to oral.
