Introduction to numerical methods for engineers (2L/1E)

*This course is offered only in German.

Course goals:

After completing this module, the students have the ability to suitable select numerical methods for solving engineering problems and implement them on the computer. They can question simulation results critically in terms of numerical artifacts. In the accompanying exercises, students learn the practical use of current numerical methods. Students will learn the possibilities with and limitations of numerical methods and thereby gain the ability to evaluate results of numerical simulations on their practical significance.

Syllabus:

Lecture:
Fundamentals of modeling with Matlab ; Solution of nonlinear systems of equations ; Approximation of functions and data ; Numerical differentiation and integration ; Solving linear systems ; Integration of Ordinary Differential Equations .
The lecture is founded on mathematical basics and will be supplemented practice-oriented. Available commercial and free software, which are suitable for solving numerical tasks from the practice of an engineer is presented.

Exercise:
In the exercise, numerical methods taught in the lecture are tested on examples of mathematical models of engineering systems and evaluated. In this way, students learn to analyze numerical problems independently and to decide which methods are best suited for the solution. In addition, these problems will get solved practically. In the exercise the widely used commercial Software Matlab is used.

Interdisciplinary Research Module for Batteries

*This course is offered only in German.

Course goals:

Students get to know the manufacturing process of Lithium-Ion batteries in detail. Based on experiments and simulations they gain knowledge about properties and functionality of batteries. Furthermore, the students improve their skills in communication, team work, scientific language and practical work.

Syllabus:

The research module imparts a deeper understanding of processes in chemical and energy engineering. The theoretical background and the practical implementation are treated by studying the manufacturing process of battery cells as well as the experimental characterization and simulation of these. The module is divided into three parts: At the iPAT, electrodes for battery cells are produced, characterized and then assembled into laboratory cells. At the InES, the cells are characterized by experiments and simulations. Based on the results, simulated experimental analysis of the thermal behaviour are carried out at the IfT.
