151-0044-10L | Engineering Tool IV/V: Computational Fluid Dynamics (CFD) with OpenFoam All Engineering Tool courses are for MAVT-Bachelor students only. Number of participants limited to 40. Only one course can be chosen per semester. | 0.4 credits | 1K | P. Jenny | |

Abstract | Participants will learn to use the open source simulation software OpenFOAM on a user level (i.e. to conduct classical CFD studies). We will also introduce the students into programming with OpenFOAM so they will be able to implement additional equations into existing solvers. | ||||

Content | OpenFOAM is a very professional open-source simulation package which is freely (CHF 0.-) available under the GNU General Public License (GPL). It consists of a vast C++ library, many different applications and additional tools. Although most of the existing applications are flow solvers, OpenFOAM can be used in many different areas, as varied as solid dynamics, electromagnetics or pricing of financial options. Most users make only use of the included applications. One particular strength of OpenFOAM, however, is that new applications and even extensions of the library can be developed in a rather compact and elegant way. | ||||

Prerequisites / Notice | Knowing C++ or at least having some experience in another programming language will be of an advantage but is not strictly required to follow this course. | ||||

151-0103-00L | Fluid Dynamics II | 3 credits | 2V + 1U | P. Jenny | |

Abstract | Two-dimensional irrotational (potential) flows: stream function and potential, singularity method, unsteady flow, aerodynamic concepts. Vorticity dynamics: vorticity and circulation, vorticity equation, vortex theorems of Helmholtz and Kelvin.

Objective | Expand basic knowledge of fluid dynamics. Concepts, phenomena and quantitative description of irrotational (potential), rotational, and one-dimensional compressible flows. | ||||
