Advanced High-Order Simulation Methods for Industrial Applications

Periodic Reporting for period 1 - ASIMIA (Advanced High-Order Simulation Methods for Industrial Applications)

Reporting period: 2019-01-01 to 2020-12-31

ASIMIA responds to the industrial requirements of “more simulation, less testing”, that manifests the need of numerical Computational Fluid Dynamics (CFD) tools offering advanced accuracy, reliability with capabilities for increased geometrical and physical complexity.
ASIMIA's beneficiaries, NUMECA and UPM-CCS together with the five ESRs of the project, aim at enhancing High Order Methods (HOM) at industrial level to cope with complex physics. HOM are based on the introduction of high degree polynomials inside each computational mesh element to improve the approximation of the numerical solution. By doing so, the accuracy (i.e. difference between numerical and real solution) is significantly improved and the numerical error decreases when increasing the polynomial order.

Although it is generally considered that HOM could form the next generation of industrial CFD simulations, the question of efficiency and adequacy of HOM approaches has still to be demonstrated for industrial applications, such as aircraft, automotive aerodynamics, thermal control, and fluid-structure interactions, which conform the main topics of study in ASIMIA. More specifically, ASIMIA proposes to enhance current turbulent models (RANS and Hybrid RANS-LES), use efficient technologies (e.g. multigrid, adaptive refinements) and large scale parallelization in multicore architectures. In addition, these methods will be extended to multidisciplinary applications coupling complex turbulent flows, multiphase, heat transfer and fluid-structure interactions with moving geometries.

By developing a new generation of CFD solvers based on HOM, ASIMIA aims at enhancing trans-sectorial transfer of knowledge through its partner organizations from aeronautical (Airbus), automotive (McLaren F1) and appliance industries (Dyson).
ASIMIA includes international and inter-sectorial training. All ESRs will be awarded a European Industrial Doctorate by the UPM-CCS and more specifically by the School of Aeronautics (ETSIAE-UPM).

The inter-sectorial side is ensured by each ESR spending a significant proportion of their time working in the industry, including secondments to three different industrial sectors, namely aviation (Airbus), car aerodynamics (McLaren Racing) and industrial appliance industry (Dyson). These three industrial partners are recognized as being highly innovative in their fields and will provide stimulating and challenging applications to the ESR’s.

The multidisciplinary character of the training will be an additional advantage, Mathematical and Computer based solutions applied to engineering design being part of this training, as well as the involvement of the ESR’s in multi-physical phenomena, such as fluid-structure or fluid-thermal interactions.

ASIMIA has recruited five ESRs and is developing a training program, which will comprise:

1. Individual Training involving research project and local training designed for specific needs of each researcher: each fellow will have a specifically tailored training.
2. Network-wide training, which involves research courses: starting from basic and moving to more advanced topics, innovation related training and complementary/transferable skills courses
3. Secondments: each fellow will work for not less than six months with two industrial partners.
Fluid mechanics and CFD are areas of expertise for the future, and the increasing demand for well-trained professionals in this field is continuously growing. ASIMIA's training and research activities are oriented to give the ESRs a broad range of opportunities in industry and academia. After finishing their training and obtaining their PhD, the ESR will be prepared to manage and create their own research group in academia or in industry. In summary, the ESRs will be prepared to play an active role in the development of European research, as they will develop understanding of how universities and industry can work together to fulfil common objectives. European industry sources indicate that there is a need for a larger number of skilled workers. Engineers need to be adaptive leaders, grounded in a broad understanding of the practice and concepts of engineering, able to make decisions and possess managerial and leadership skills. The training offered by ASIMIA will help the ESRs to address the complex engineering and social problems of the future.

The aim of this Industrial European Doctorate is to provide the young researchers with a set of skills, which will contribute to their personal development, will improve their ability to undertake focused research, and will help to transmit the results of their work to wider audiences, as well as to develop an understanding (through learning about impact of their research) of how important is science to society. The program offers skills relevant to both the research undertaken within this project and to career beyond it.
Long term ability of Europe to develop its own products of high technical quality heavily relies on European research, oriented towards results with direct industrial applications. ASIMIA seeks to strengthen European innovation capacity in the area of simulation methodologies. In this line, we focus on excellence in education and skills development as one of the key points to make Europe more competitive by 2020.
