Aim

Gases and liquids in motion are found in a vast number of technical applications.
The course should give a thorough understanding of the flow phenomena that occurs in technical devices, and give
good knowledge about methods that are used to solve realistic problems.

Learning outcomes (after completion of the course the student should be able to)

- conduct industrial development work in the area of fluid mechanics
- apply control volume formulations, differential formulations and similarity laws
- account for basic phenomena and methods for treating turbulent flows and compressible flows

28. Use von Karmans integral relation

29. Explain flow separation (separated cylinder flow)

30. Explain how to delay or avoid separation

31. Derive the boundary layer formulation of the Navier-Stokes equations

32. Understand and explain displacement thickness and momentum thickness

33. Understand, explain and use the concepts drag, friction drag, pressure drag, and lift

34. Understand and explain how the shape and surface roughness of an object affects drag

35. Measure forces on an object in a flow

36. Define and explain vorticity

Content

Basic concepts
Control volume relations for mass, momentum, angular momentum and energy
Differential equations for mass, momentum and energy
Dimensional analysis and similarity
Pipe flow
Turbulence
Boundary layer flow
Compressible flow
Design task 2 is covered by a CFD-tutorial where a 2D mesh is created and used to simulate the boundary layer (laminar and turbulent) on a flat plate. The software ICEM will be used for the meshing and Fluent to solve the equations describing the flow field. Measured boundary layer profiles in a wind tunnel using a flat plate are going to be provided. This data should be compared to the CFD simulations.
