Felix Klein Academy 2022 Fall School

Once a year, the one-week autumn school for scholarship holders of the Felix Klein Academy takes place at our institute. Here, the students work in groups together with us on various projects. In addition to tasks from the working practice of the institute, the groups can also expect exciting technical lectures and a varied leisure program. 

The groups are made up of math students from different semesters. Their task is to translate a real problem into a mathematical one. They evaluate the model that is developed in the process and check the solution for its relevance. At the end of the week, they present their results in a plenary session. The participants could choose in advance between four projects with different topics:

1st Group With the Topic: Optimization of District Heating Networks

Supervisor: Johanna Heidrich, Department »Transport Processes« (TV), Fraunhofer ITWM 

Supplying households with thermal energy via district heating networks offers the possibility of harnessing waste heat from electricity production or industry. District heating networks are closed-loop systems in the sense that water is pumped from cogeneration plants through a pipe system to consumers and flows back through pipes laid in parallel. Energy is transferred by heating the water at the plant and transferring heat through a heat exchanger to the domestic network at the consumer. Within the network, the flow of energy is not dictated by the network operator, but results from the energy drawn by the consumers. To ensure security of supply and minimize energy losses in the network, the feed-in temperature at the plant must be adjusted accordingly. Preheating in the hours before a peak, filling the grid with water of maximum temperature, allows the peak demand to be met with a uniform feed-in power.

In this workshop, we first consider an abstracted model with a heat source, a pipe, and a consumer that has a periodic consumer profile with the two typical peaks at morning as well as evening time. Now, for such a demand with peaks, what is the optimal feed-in temperature at constant feed-in power? The first group takes a closer look at this question together.

Artificial Intelligence Workshop Visit also in the Program

Concurrent with this year's Fall School, the workshop Mathematics in the Artificial and Biological Intelligence with AI expert Prof. Dr. Illia Horenko will be held Wednesdays through Fridays.

Prof. Dr. Illia Horenko has been a new professor at the Department of Mathematics at Rheinland-Pfälzische Technische Universität Kaiserslautern-Landau (RPTU) since July 1, 2022. There, he represents the teaching area of Artificial Intelligence. He has already been connected with Fraunhofer ITWM through projects for several months. During the Felix Klein Fall School, he will present his field of work in more detail.

The participants also went on a non-mathematical excursion to Trifels Castle in Annweiler:
