Course paper / final thesis Experimental analysis of an electrically charged latent heat storage unit and comparison with simulation results Master´s in Chemical Engineering, Mechanical Engineering, Physics or similar

Start your mission with DLR.

The German Aerospace Center (DLR) is the national aeronautics and space research centre and the space agency of the Federal Republic of Germany. Here, 8000 employees work together on a unique variety of topics in the fields of aeronautics, space, energy, transport, digitalisation and security. Their missions range from basic research to the development of innovative applications and products for tomorrow. Cutting-edge research requires excellent minds – particularly more females – at all levels, who fully achieve their potential in an inspiring environment. Launch your mission with us.

For our Institute of Engineering Thermodynamics in Stuttgart we are looking for a

Experimental analysis of an electrically charged latent heat storage

Your mission:

The conversion of electricity to heat, so-called power-to-heat, is one of the ways that increased fluctuations and the therefore necessary flexibility in the electricity grid can be compensated for. This energy can be stored thermally and dispatched when necessary. One way to store thermal energy is in latent heat storage systems, in which the storage material changes phase between solid and liquid during charging and respectively reversed during discharging.

In this project, your goal is to experimentally test a new storage unit, which has already been assembled. The experiments must be planned, executed and analyzed. In parallel, the results will be compared to the existing design parameters and the simulation models and any discrepancies analyzed. The goal is to determine the effectiveness of the design and if the design parameters and models were achieved. As a last step, further possibilities for optimizing and better understanding the concepts will be investigated.

The work can be outlined as follows:

• orientation in characteristics and operation of latent heat storage units
• planning of the experiments for the storage unit
• familiarization with the simulation models
• execution of the experiments with parameter variations
• analysis of the results
• validation and, if necessary, adaptation of the model
• comparison and further development of the concept

Your qualifications:

• Major in chemical engineering, mechanical engineering, physics, etc.
• very good comprehension of thermodynamics and heat transfer
• interest in simulative as well as experimental work
• conscientious, structured and independent work ethic
• good English skills
• good FEM proficiency
• experience with ANSYS

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (m/f/non-binary). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
