J.B. Wahl to present at MoRePaS 2018

In News by François Der Hovsepian

Jean-Baptiste Wahl will present at the annual MoRePaS Conference (Model Reduction of Parametrized System), in Nantes, France on June 13, 2018 from 11:50 AM to 12:15 PM. About 130 researchers are expected to attend the conference. He will talk about model order reduction for aerothermal simulations.


In this model, we consider the coupling between the incompressible Navier-Stokes equations and an advection-diffusion equation for the temperature. Streamline diffusion and shock capturing methods are introduced to deal with the numerical instability issues appearing in high Reynolds simulation.


The non-linearity and the complexity of the stabilization operators are treated by a multi-component empirical interpolation method for discrete operators. In this presentation, we will particularly focus on the recent developments in the Feel++ reduced basis framework: we propose a simultaneous construction (SER) for the reduced basis and the affine approximation of the non-linear stabilization operators. As an illustration, we present an application of a cooling system of a printed circuit board with different heat sources.
