Assessment of numerical aspects using LES in particle separation devices

Numerical simulations can be a powerful tool for the design and optimization of Foreign Object Debris (FOD) protection and separation devices. This work aims to study the relevance and influence of different modelling and numerical aspects in simulations of FOD devices using Large Eddy Simulation (LES) modelling. The results show that in LES some numerical aspects can be critical and must be carefully considered aiming to obtain accurate and reliable results. It is presented how some models affect the physics of the phenomena involved in these kind of flows as well as their impact on the accuracy of the simulations.Peer ReviewedPostprint (published version
