Course content

Derivation and discussion of the basic equations for viscous fluid flow, including heat conduction and compressibility. Molecular background for viscosity. Exact solutions like; Couette flow, Stokes 1. - and 2. problem, Hiemenz stagnation point flow. The boundary layer approximation, Blasius and Falkner-Skan solutions, effects of pressure gradient; Pohlhausen - and Thwaites methods, criteria for separation. Non-steady boundary layers. Stability of laminar flow, Orr-Sommerfeld equation and transition to turbulence.
Examples from internal flows, and from flows around bodies.

Learning outcome

Knowledge:
The course provides the student with knowledge about:
- Formulating and solving problems in fluid mechanics where viscosity and heat conductivity are of importance, in particular at high Reynolds numbers where the boundary layer approximation applies.
- Primary focus is on the laminar flow regime and stability and transition to turbulence.
- Quantitative methods for classical cases, such as Stokes problems, stagnation point flow, Blasius and Falkner-Skan problems, and integral methods for other boundary layers with pressure gradient and possible separation. Qualitative and quantitative aspects of the stability theory for parallel flows in simple geometries.
- Applications for internal flows in pipes and channels and for simple process components, as well as for external flow around wing profiles.
- The course gives the student insight about:
- Application of basic theory for viscous and thermal boundary layers to estimate spatial distribution of flow properties, as well as to determine friction forces and heat transfer between fluid and solid boundaries in a mechanical engineering context.

Skills:
The course should enable the student to:
- Compute critical parameters like friction factor and heat flux at wall, in addition to local details in the flow field, for systems of simple geometries.
- To some extent design process components for specific purposes from performance requirements, such as pressure recovery and thermal development in the flow field.

General competence:
The course should give the student insight on:
- Systematic applications of the general theoretical background for thermo-viscous flows in a technological context, in particular for high Reynolds numbers.
- Coupling to potential theory in elementary fluid mechanics, and construction of composite solutions for complete flow domains.
- Use of standard mathematical tools for analyzing and solving real-flow problems, in particular in the area of mechanical engineering.
