Course specific prerequisites
Thermodynamics and Calculus in several variablesAim
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)

- Use von Karmans integral relation
- Explain flow separation (separated cylinder flow)
- Explain how to delay or avoid separation
- Derive the boundary layer formulation of the Navier-Stokes equations
- Explain displacement thickness and momentum thickness
- Explain and use the concepts drag, friction drag, pressure drag, and lift
- Explain how the shape and surface roughness of an object affects drag
- Measure forces on an object in a flow
- Define and explain vorticity
- Explain basic concepts of compressible flows (the gas law, speed of sound, Mach number, isentropic flow with changing area, normal shocks, oblique shocks, Prandtl-Meyer expansion)
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.
