Institute of Engineering Thermodynamics (Friedrich-Alexander University Erlangen-Nuremberg)

Founded in 1743 with today almost 40,000 students (3,550 of them international students) and about 570 professors and 14,000 members of staff, Friedrich-Alexander University (FAU) is one of the largest universities in Germany. With its five faculties, FAU offers an almost unique scope of subjects with 263 study course, about 50 international. Over the last decades, the University has established its reputation as a top-ranking institution in cutting-edge research. It is firmly anchored in a close network of interdisciplinary co-operations. The faculty of engineering is regularly ranked as one of the top-five universities in Germany with respect to funds of the German Research Foundation per professor.

The research in the institute for engineering thermodynamics (LTT) in the faculty of engineering covers a broad spectrum, starting with basic investigations e.g. on transport processes, particle formation and combustion processes up to the improvement of technical procedures, e.g. in heat engineering or motor combustion. A major methodological focus of the LTT is the development and application of optical, mostly laser-based measurement methods. In all research areas, there are close co-operations with national and international partners from academia and industry. The LTT is involved in institutions of the Excellence Initiative, namely the Erlangen Graduate School in Advanced Optical Technologies (SAOT) and the Cluster of Excellence Engineering of Advanced Materials (EAM).

Role in the project

In addition to the role as consortium leader with the tasks in the project organization, milestone planning, reporting and publication of the project results, as well as the promotion of the exchange in the project and beyond the project, FAU specializes in laser diagnostics, flow visualization and thermal measurements. Specific test configurations will be designed and assembled for the project to investigate heat transfer and flow fields on the subsystem and system levels. Geometrical configurations promoting longitudinal and cross-flow vortices will be designed and manufactured. Optical and metallic test-piece counterparts will be fabricated to facilitate the flow field visualisation and macroscopic measurements. The required heat flux, replicating the battery heating during charge/discharge, will be provided by electric heaters embedded in the metallic surfaces. For the heat-flux measurement, ultrafast (~1μs response time corresponding to the high resolved PIV flow-field measurements) Atomic Layer Thermopile (ALT) sensors available to FAU will be calibrated for the range of heat fluxes relevant to battery cooling (up to 50 kW/m2). Blended, standardised non-Newtonian liquids and nanofluids with different polymers and nanoparticles will be investigated. The well-defined liquid properties will allow the flow characterisation through accurate non-dimensional numbers (e.g. Reynolds and Nusselt numbers) in the experimental tasks.

Furthermore, LTT will overtake the design, manufacturing and testing of a battery package prototype. The prototype will be evaluated in terms of performance and parasitic power. The performance of battery thermal management system will be compared against baseline cases with conventional geometries and heat transfer liquids.

CITY, University of London

City, University of London is a global University, part of the University of London, committed to academic excellence with a focus on business and the professions and a central London location. City’s School of Mathematics, Computer Science & Engineering has been leading education and research in engineering and mathematics for more than a hundred years. The Department of Mechanical Engineering & Aeronautics is the home for the ThermoFluids Research Centre (TFRC) and the Aeronautics and Aerospace Research Centre, the low-turbulence tunnel of which is part of the UK’s National Wind Tunnel Facility. TFRC maintains strong links with automotive, fuels and fuel additives industries that actively build our international reputation. Since 2013, TFRC has coordinated more than 17 EC-funded research grants. The 2014 Research Excellence Framework (REF) showed a significant improvement in our research standing, with 79% of appointed staff rated as world-leading and internationally excellent. The TFRC is committed to interdisciplinary research methods needed for understanding the intrinsic physical phenomena in thermo- and fluid flow processes, as realised from molecular/nano- to macro-scales and their wide range of engineering applications addressing global challenges such as energy efficiency, emissions reduction and bio-engineering applications aiming towards the well-being. The project partners, members of City’s TFRC, hold more than 20 years of experience and extensive knowledge in multiphase flows, both by using numerical techniques and dedicated experimental facilities. Computational techniques developed in-house can handle diffuse/sharp interfaces, compressible multi-material, real-fluid thermodynamics with moving geometries, Fluid Structure Interaction (FSI) and non-Newtonian fluids. Experimental investigations at CITY involve high-speed imaging with visible spectrum light and quantitative measurements of density using X-rays (in collaboration with Argonne National Laboratory in the US).
