We will continue with our Seminar Series on October 30th, 2023.
On site: 3.S1.08 (Biblioteca Rey Pastor)
For the next event in the Aerospace PhD Seminar Series, we will have the pleasure of hosting Dr. Gonzalo Arranz, a postdoctoral associate at the Massachusetts Institute of Technology.
The event will take place in the room 3.S1.08 (Biblioteca Rey Pastor) on Monday, October 30th at 1pm and will be streamed (Online).
Gonzalo Arranz obtained his PhD in 2021 by University Carlos III de Madrid, where he focused on the fluid dynamics of bio-inspired locomotion problems. He is currently a postdoctoral associate at MIT, in the Department of Aeronautics and Astronautics. Currently, his research is focused on the development of subgrid scale models for large eddy simulations, and the study of causality in turbulent flows using information theory.
“A subgrid scale model for Large-Eddy simulations using Building-Block flows”
Abstract:
Computational fluid dynamics (CFD) has played a key role in the modern aerospace industry for the aerodynamic design of aircraft. In recent years, wall-modeled large-eddy simulation (WMLES) has gained traction as an alternative to traditional lower-fidelity models, such as Reynolds-averaged Navier-Stokes methods.
However, even state-of-the-art WMLES models are still unable to comply with the stringent accuracy requirements and computational efficiency demanded by the industry. This calls for the exploration of new venues to develop robust and accurate models for wall-modeled large-eddy simulation.
In this talk, we will present a new data-driven subgrid scale model based on the concept of building blocks. The main assumption is that simple canonical flows (building blocks) contain the essential physics to provide accurate predictions in more complex flows. Apart from digging into the details of the model, we will show its application to complex geometries relevant to the aeronautical industry.
The seminars will begin at 1pm and will take place in the Auditorium Salón de Grados (Padre Soler)
