dc.description.abstract | We present a successful deployment of high-fidelity Large-Eddy Simulation (LES)
technologies based on spectral/hp element methods to industrial flow problems, which are characterized by high Reynolds numbers and complex geometries. In particular, we describe the numerical
methods, software development and steps that were required to perform the implicit LES of a real
automotive car, namely the Elemental Rp1 model. To the best of the authors’ knowledge, this simulation represents the first high-order accurate transient LES of an entire real car geometry. Moreover,
this constitutes a key milestone towards considerably expanding the computational design envelope
currently allowed in industry, where steady-state modelling remains the standard. To this end, a
number of novel developments had to be made in order to overcome obstacles in mesh generation
and solver technology to achieve this simulation, which we detail in this paper. The main objective
is to present to the industrial and applied mathematics community, a viable pathway to translate
academic developments into industrial tools, that can substantially advance the analysis and design
capabilities of high-end engineering stakeholders. The novel developments and results were achieved
using the academic-driven open-source framework Nektar++. | en_GB |
