Activity: Talk or presentationTalk or presentation at a workshop, seminar, course or other meeting

Description

The field of external aerodynamics is a broad field of engineering and its computational study poses significant challenges, particularly when dealing with intricate phenomena such as strong body-vortex interactions. It is crucial to develop efficient and accurate tools to tackle such cases successfully. This presentation introduces a hybrid Eulerian-Lagrangian solver that focuses on the realm of external aerodynamics. This coupled solver leverages the benefits offered by both the Eulerian and Lagrangian approaches. Specifically, the Eulerian solver is employed to resolve the vicinity of solid boundaries, while the Lagrangian solver efficiently evolves the downstream wake, minimizing artificial diffusion.

OpenFOAM is utilized for the Eulerian component, while a Vortex Particle Method is employed for the Lagrangian aspect. The presentation focuses on two main topics. Firstly, it explores the coupling strategy employed in the hybrid code and presents the validation process of this approach. Secondly, it discusses the modifications made to the pimpleFoam solver of OpenFOAM to achieve an efficient coupling with the in-house Vortex Particle Method code. A class called EulerianPimpleFoam replaces the pimpleFoam module, facilitating the incorporation of coupling steps between different Eulerian time-steps. The advantages and challenges associated with this approximation will be examined and discussed upon.
