Abstract: This seminar will present the ongoing research under

development at IME on High-Order Numerical Simulations of Compressible

Flows, focussing on low Mach number flows. It will be divided into

four major topics: 1) PIRK (Preconditioned Implicit Runge-Kutta)

Methods for the simulations of high-order unsteady compressible flows;

2) Optimal low Mach preconditioning matrixes for improved efficiency

of preconditioned density-based methods; 3) PTD (Physical-Time

Damping) method for the generation of steady-state solutions and 4)

 High-order global boundary conditions for unsteady simulations.
