Linear model of a high temperature heat pump based on the closed Brayton cycle process
As part of my education at the INSA Hauts-de-France, I did my four-and-a-half-month internship at the Cottbus DLR Institute of Low-Carbon Industrial Processes. During this internship, I acquired new knowledge by reading many scientific articles and enabled me to challenge myself and apply some of my mathematical and Python skills. I was guided by two tutors, one belonging to the mathematical field, another one to the field of energy technology. In particular, the topic was at the interface of two research teams of the Institute. Due to corona pandemic, I had to make a small online presentation several times a week to my tutors to give them an overview of my breakthroughs and ask them for their opinion on issues I had to deal with. The objectives of the internship were to understand the short-term heat pump behavior and to develop a linear dynamical system which captures the dominant physical characteristics of the high temperature heat pump developed by the DLR institute.

Numerical investigation of the machine frame of a high temperature heat pump
My time at the DLR Institute of Low-Carbon Industrial Processes in Zittau/Cottbus was special in two ways. First, I was able to be a part of a very young team during the founding phase of the institute. Firmly entrenched modes of operation did not exist at my time, which meant that I was treated respectfully and without bias as part of the team. On the other hand, the work has been shaped by the current pandemic. I have been able to experience how home offices can work from a work perspective. Against this background, I dealt with the static calculation of the frame for the main components of the Cottbus high-temperature heat pump. The results of the calculations were evaluated and were taken into account in the design process that took place at the same time. The steel frame developed in this way is currently being manufactured and will soon be used as the main supporting structure - a very satisfying, practical activity for me as an engineer.

Development of an optimization algorithm for the direct reduction of iron ore
As part of my bachelor's degree in mathematics at BTU Cottbus-Senftenberg, I completed a six-week internship at the DLR Institute of Low-Carbon Industrial Processes. Due to the Sars-CoV-2 pandemic, I spent my internship in the home office. My first task was to familiarize myself with the topic "reduction of iron ores" and the corresponding optimization methods by means of scientific papers. The goal of the project I was allowed to work on was to develop a model that depicts the reduction of iron ores, which is necessary for iron production. The mathematical basis was a one-dimensional model of an iron ore pellet. There were a lot of parameters that influence the model and an optimization algorithm that adjusts these parameters so that the model reproduces the measured values as well as possible. My task was to reduce the runtime of the model calculation. My main activity was to program an alternative algorithm so that the optimization could be done in less time.

Further development of a heat pump - comparison and simulation of heat pump and immersion heater
As part of my mechanical engineering studies, I completed a 16-week internship at the DLR Institute of Low-Carbon Industrial Processes in Zittau. Through the internship I was able to apply and understand my learned knowledge from the university on real plants. The processing of my tasks brought me closer to the handling of industrial software. During my internship I had a supervisor with whom I consulted weekly on the progress of my tasks. If I had any questions or problems, I could rely on the helpfulness of my colleagues. My task at DLR was to simulate the existing demo heat pump and to create an illustrative comparison to heat generation by heating resistors. To create the comparison and the simulation, measured values were recorded on the heat pump and an immersion heater, as an example of a heating resistor. Both heat generators were used to heat 1.4l of water to 40°C. The water temperatures, the amount of energy consumed, as well as the time required for this were measured in order to make a comparison. The amount of energy consumed was 22-23Wh for the heat pump and 39-44Wh for the immersion heater.
