### Content, Learning Outcome and Preconditions

#### Content

In this module, knowledge in computational fluid dynamics simulation is taught via theoretical and practical methods. The content is divided into three sections:

1. Basics of numerical methods: linear and non-linear algebraic systems of equations; optimization methods; interpolation and approximation; differentiation and integration; ordinary and partial differential equations, difference methods, finite volume methods

2. Numerical fluid mechanics: Equations of fluid mechanics; turbulence modelling; meshing; heat and mass transfer; multiphase and multi-component flows; chemically reacting flows.

3. Computer exercises: geometry construction, meshing, simulation of a thermal process, simulation of multi-component flows (stationary/stationary) etc.

#### Learning Outcome

After participating in the module, students are able to...

- classify and evaluate numerical problems with the acquired knowledge and to recognize and apply the respective solution methods.
- understand specific problems in the field of CFD and to solve/optimize them by setting up a simulation.

#### Preconditions

Knowledge in higher mathematics (analysis, algebra), basics in fluid mechanics.

#### Learning and Teaching Methods

The module consists of a series of lectures with media support through a PowerPoint presentation. This gives students a comprehensive overview of numerical methods and their fields of application. The lecture slides are made available to the students. The students will get an insight into modern CFD software that is used in today's research and development through exercises. The practical examples are partly solved by hand or presented live by the lecturer. The computer exercises are instructed by provided handouts and personally supervised. The students learn to gain a deeper understanding of typical engineering tasks in power engineering by CFD simulation of thermal processes. In addition, they learn to recognize and apply numerical problems (in the context of power engineering and thermal processes) and the respective solution methods as well as to understand specific problems in the field of CFD and to solve/optimise them by setting up simulations.

### Module Exam

#### Description of exams and course work

In an oral examination (individual examination, oral, about 30 minutes per participant) it is tested whether the students can apply the imparted competences to simple problems. For example, the students should demonstrate that they are able to recognize and apply numerical problems (in the context of energy technology and thermal processes) and the respective solution methods, as well as to understand specific problems in the field of CFD and to solve/optimize them by setting up a simulation.

Auxiliary means are not allowed during the examination.

The final grade consists of the following examination elements:

- 100 % oral final examination

The final grade is composed of the following examination elements:

#### Exam Repetition

There is a possibility to take the exam in the following semester.
