I-BAT, a research and innovation project aims to develop a novel advanced methodology for efficient cooling of Electrical Battery Packs for the Electric Automotive Field. The project is funded by the EU Framework Programme for Research and Innovation HORIZON 2020. The project duration is 01.10.2020 – 30.09.2024.
The proposed submerged-cooling Battery Thermal Management System (BTMS) aims to a significant increase in heat flux that can be handled at a specific temperature difference. From a scientific/flow-physics point of view, this will be achieved by manufacturing and testing new viscoelastic nanofluids with efficient thermal and flow performance. The collaborative effect of viscoelasticity and nanoscale heat-transfer phenomena has not been investigated in this context and targeting applications for EVs. Information for their rheological properties that cannot be obtained by experimentation or is limited, can be supplemented for a multi-parametric domain by numerical modelling. Synthetization of heat transfer (HR) fluids relies on specific estimations provided by various numerical models, which in turn account for the contribution of viscoelastic stresses (i.e. by Phan-Thien-Tanner models) and shear-thinning effects (i.e. through Carreau-Yasuda Modelling approaches).
