'Towards the use of Lattice Boltzmann Method for full aircraft noise prediction’
Abstract
The current status of Lattice Boltzmann simulation of aircraft noise generation and radiation at component level is outlined with emphasis on the most recent validation studies carried out by Exa Corporation using the CFD software PowerFLOW. After a preliminary overview of the underlying elements of the LBM-VLES methodology and its deployment in the aerospace ?eld to tackle aerodynamic, acoustic and thermal applications, the presentation focuses on the problem of airframe (landing gear and high-lift) and engine (jet and fan) noise prediction. The current software reliability status is critically reviewed in relation to the main uncertainties affecting the numerical models and the experimental data. An outlook on the use of the LBM for the computation of noise certi?cation level of a full aircraft is ?nally provided by presenting the ?rst version of a demonstration platform developped by Exa to trace and push the current limits of the noise prediction capabilities, both in terms of physical modelling and software requirements.
Speaker Biography
Damiano Casalino (DC), PhD in fluid-dynamics (Turin Polytechnic) and acoustics (Ecole Centrale de Lyon) has research interests in aeroacoustics that cover frequency-domain CAA for duct acoustics and installation effects, sound propagation in sheared flows, integral methods, stochastic noise generation, advanced experimental techniques for space launcher noise, helicopter trajectory optimization, vortex-airfoil interaction noise, liner optimization. Since 2012, DC is employed as technical director of aerospace aerocoustics by Exa Corporation, with a specific focus on the industrial exploitation of the lattice Boltzmann method for airframe and engine noise prediction. DC is author and co-author of about thirty archival journal publications in the field of aeroacoustics.
