SG2214 Fluid Mechanics 7.5 credits
Strömningsmekanik
All fluid flows are governed by a single set of partial differential equations, the Navier-Stokes equations. This includes for instance, the aerodynamics of bumble bees and aerospace planes, the turbulence around vehicles and in the atmosphere and the convection in the sun and around a human body. The course is an in-depth introduction to fluid mechanics, with an emphasis of understanding fluid phenomena using on the Navier-Stokes equations. The equations are derived in detail and numerous examples of solutions are presented. Fluid Mechanics also has many important applications in engineering, geo- and astro-physics and bio-physics, for example, which makes this course ideal as a starting point for students with a varied interest in applications.

Intended learning outcomes
- The student shuold be able to formulate mathematical models of fluid mechanical phenomena, and make relevant approximations.
- The student should be able to apply the these models (numerically or theoretically) and interprete the result.
- The student should get a basic preparation for the future ability as a master of engineering to work with computational fluid mechanics in technical applications.
Course main content
The student should be able to
- derive the Navier-Stokes equations and explain the meaning of its terms, including the stress and deformation rate tensors
- describe the method of transferring from compressible to incompressible equations
- compute the flow field for a number of so called exact solutions
- derive the vorticity equation and give a physical explanation of its terms
- use the concepts of stream function, velocity potential and apply the Bernoulli equation
- discuss the principles of and derive the boundary layer approximation of the Navier-Stokes equations, and to give self similar solutions of these equations including simple thermal boundary layers
- describe the phenomena of separation of streamlines.
- describe simple phenomena in turbulence, as e.g. turbulent stresses.
- derive the Reynolds averaged equations
- suggest methods to measure the velocity in a flowing medium
