Article
For complex engineering and scientific applications, Computational Fluid Dynamics (CFD) simulations require a huge amount of computational power. As such, it is of paramount importance to carefully assess the performance of CFD codes and to study them in depth for enabling optimisation and portability. In this paper, we study three complex CFD code...

We describe the procedure for the optimization of the fluid-structure interaction (FSI) carried out for the P180 Avanti EVO vehicle, designed and manufactured by Piaggio Aerospace, performed in the framework of the Experiment n. 906 of the FORTISSIMO 2 research project. In particular, the effect of a set of modifications of the winglet shape, that...

A family of space- and time-optimised prefactored compact schemes are developed that minimise the computational cost for given levels of numerical error in wave propagation phenomena, with special reference to aerodynamic sound. This work extends the approach of Pirozzoli [1] to the MacCormack type prefactored compact high-order schemes developed b...
Conference Paper
Full-text available
A flexible and versatile full-scale CFD modeling strategy of the airflow in a road tunnel is described. As applied to the case of the Mont-Blanc tunnel, the model includes the entire tunnel length and main characteristic elements of its hybrid ventilation system, including lateral air intake, longitudinal jet fans and air extraction vents. Each of...
Conference Paper
This paper presents an extension of the Tam and Dong solid wall boundary condition that combines the established non-penetration physical condition with a further restriction on the wall-normal velocity gradient. This results in a wall boundary condition in the form of a second-order partial differential equation which is satisfied analytically by...

Article
Full-text available
The large disparity between the time and length scales of an acoustically active flow field, and the ones of the resulting generated acoustic field, is an issue in computational aeroacoustics (CAA). Numerical schemes used to calculate the time and space derivatives in CAA should exhibit a low dispersion and dissipation error. This paper presents th...

Full-text available
A variety of aeroacoustic problems involve small-amplitude linear wave propagation. High-order schemes have the accuracy and the low dispersion and dissipation wave propagation properties that are required to model linear acoustic waves with minimal spatial resolution. This review presents a selection of high-order finite difference time-explicit s...
