By Samuele Rubino (Seville University) The aim of this secondment was to numerically test in the framework of POD (Proper Orthogonal Descomposition)-ROMs (Reduced Order Models) an efficient time-splitting approximation of the Navier-Stokes equations with open boundary conditions already performed for Finite Volume FOMs (Full Order Models)
By Anna Ivagnes (SISSA) Finite Element (FE) simulations are often characterized by spurious oscillations and poor accuracy when dealing with convection-dominated flows and coarse mesh resolutions. When these phenomena manifest, numerical stabilization techniques turn out to be useful to alleviate the spurious oscillations and improve the results of Full Order…
Volkswagen sent a secondment to Inria with the purpose of the secondment is to tackle challenges of residual minimization-based model order reduction in car aerodynamics. To that end, a Reduced Order Model (ROM) based on residual minimization (ResMin-ROM) was applied to a backward facing step test case.
SISSA had a secondment to Virginia Tech in November 2023. The purpose is to investigate machine learning methods and optimization algorithms to find theoptimal filtering and relaxation parameters in the Evolve-Filter-Relax (EFR) regularization technique. This technique is applied to a benchmark in convection-dominated CFD simulations, in particular, the flow past…
S. Rubino from University of Seville had a month secondment at Valorem in July 2023 with the purpose: Development, numerical analysis and implementation of reduced order models for the simulationof complex flows with dominant convection. Development, numerical analysis and implementation of efficient time-splitting POD-ROMs for theNavier-Stokes equations with open boundary…
ESTECO sent two researchers o Inria in July 2023 to investigate how to combine Uncertainties Quantification (UQ) techniques with Reduced Order Model (ROM) and study the use of ROM within an MDO framework for industrial applications.
C.Núñez Fernández from Virtualmech had a month of secondment in July 2023 at Inria to work onTime-Splitting method for Navier-Stokes equations for Finite Element Method in order to do a Full Order Model (FOM) and a Reduced Order Model (ROM).
E. Temellini (Politecnico di Milano) had a 3 month (February – May 2023) secondment at Virtualmech on the topic of Model reduction and mesh adaptation techniques for VMS – Smagorinsky turbulence model.

UCSC sent a team of 2 persons to Virginia Tech from January to February 2023 for a secondment to work on regularized ROM (Reg-ROM) for Navier-Stokes and Burgers’ equations. In particular, the team formulated a new Reg-ROM, i.e., the approximate deconvolution Leray ROM (ADL-ROM). Our numerical investigation is meant to…
