Multi-physics Modeling Approaches for the Simulation of New Generation Propulsion Systems
In recent years, the automotive industry has experienced a significant transition towards innovative and alternative propulsion technologies. Novel hybrid electrified internal combustion engines (ICE) have become the standard solution for new production vehicles. Simultaneously, the first generation of battery electric vehicles (BEV) has been deployed for mass production and fuel cell (FC) vehicles have been demonstrated to be a viable solution for a multi-technology decarbonization path. Within this scenario, Computational Fluid Dynamics (CFD) tools have assumed a pivotal role in the design and implementation of new advanced technological solutions, leading to a significant benefit in terms of time and cost saving. This required a significant improvement in the modeling capabilities, in order to deal with the complexity of the different physical problems involved, which are often coupled together, leading to a complex multi-physics framework. This special track aims at gathering innovative contributions in the development and application of multi-physics CFD approaches for the modeling of future power units based on hybrid ICEs, batteries and fuel cells. Contributions could cover advancements including, but not limited to: thermal management of electric motors and batteries, electrochemical simulation of fuel cells and batteries, innovative combustion processes and after-treatment systems in internal combustion engines. Simulation approaches could be addressed at the single component, system or vehicle scale. Moreover, multi-scale analyses are encouraged.
