151-0027-10LEngineering Tool IV: Programming with LabView Restricted registration - show details
Only one course can be chosen per semester.

All Engineering Tool courses are for MAVT-Bachelor students only.
0.4 credits1KL. Prochazka, T. Rösgen
AbstractAn introduction is given to the LabView programming environment. The basic concepts of "virtual instruments" and data flow programming are presented. Computer-based exercises are solved during class. A simple electronic data acquisition module is used to demonstrate basic concepts of interface management and data acquisition.
ObjectiveIntroduction to the LabView programming environment.
Understanding of fundamental concepts: virtual instruments, data flow programming, control structures, data types etc.
Development of basic programming skills using in-class exercises on computers.

151-0119-00LMolecular Fluid Mechanics1 credit1GS. Schlamp, T. Rösgen
AbstractTheory, applications, and simulation methods of fluids away from the continuum limit. The focus is on rarefied gases, but applications to micro-fluid mechanics will also be addressed.
ObjectiveFluids are usually treated in the continuum limit. For example, this assumption underlies the Navier-Stokes equations. For certain applications, this is not appropriate; when either the gas becomes so dilute that the molecules' mean-free path is comparable to external length scales (such as for hypersonic flight in the upper atmosphere), or when the external length scales become so small as to approach the molecular length scales (microfluid mechanics).

Students will learn:
- Relationship between the molecular nature of fluids and macroscopic quantities
- Underlying assumptions and approximations of continuum fluid mechanics in general and the Navier-Stokes equation in particular
- Theoretical and numerical approaches to treat non-continuum flows
ContentMolecular description of matter: distribution functions, discrete-velocity gases, relation to macroscopic quantities

Kinetic theory: free-path theory, internal degrees of freedom.

Boltzmann equation: BBGKY hierarchy and closure, H theorem, Euler equations, Chapman-Enskog procedure, free-molecule flows.

Collisionless and transitional flows

Direct simulation Monte Carlo methods

Hypersonics

Applications
Lecture notesThe class will follow the text book fairly closely.
