COMPUTATIONAL GAS DYNAMICS

Course objectives

One of the greatest difficulties encountered in the practical use in terms of engineering applications of computational fluid dynamics is the competitiveness of tasks, and related problems, which are by their nature very different. To name a few: the choice of computational mesh, solution algorithm, turbulence model, etc. Therefore, the training objectives will focus on the knowledge and understanding of a broad spectrum of numerical methods, physical models and analysis techniques relevant to aerodynamic design in the compressible regime, as well as on the acquisition of the ability to identify the physical problem of interest, the choice of an appropriate approach for numerical modeling and the critical evaluation of the results obtained. In addition, great emphasis will be placed on a project, hopefully a group project, aimed at the solution/simulation of a specific problem. This will address virtually all phases of the CFD workflow, pre-processing, resolution and post-processing. The team will have to organize meetings, manage resources, handle task dependence, report on calculations, and conduct comprehensive analysis. The group project is central to this course, as it creates a virtual consulting environment, bringing together students with diverse backgrounds to solve a real problem. Problem solving and project coordination must be undertaken on an individual and team basis. Students will also develop interpersonal skills needed to pursue their future careers as engineering and technology leaders. At the end of the project, the team will give a presentation in which they will outline the problems encountered and the results achieved.

Prerequisites
Fundamentals of gas-dynamics necessary for the study of propulsion systems, launch vehicles and re-entry vehicles Skills acquired in the Gas-Dynamics course
Books
Ferziger and Peric: Computarional Methods for Fluid Dynamics - Springer
Frequency
face-to-face, except in exceptional cases provided by faculty/University rules by video conference
Exam mode
The final examination consists of the execution of a project, to be developed hopefully in a working group, aimed at the solution/simulation of a specific problem. This will cover practically all phases of the CFD workflow, pre-processing, resolution and post-processing. The team will have to organise meetings, manage resources, manage task dependency, report on calculations and conduct comprehensive analyses. The final project presentation will form an important part of the overall evaluation.

Lesson mode
Frontal teaching with theory and many practical exercises. The students, with the help of the instructors, will have to carry out some practical exercises that will familiarize them with the engineering tools used. The last part of the course is dedicated to a project to be carried out in groups with the support of the teachers.
