AMICAL Project: Modeling Tools for Low-Noise Fan Technologies

Low-noise fan technologies must be developed for next-generation UHBR (Ultra High By-pass Ratio) engines. The design of these innovative fan technologies is highly dependent on the capability of the modeling tools to predict the aeroacoustics phenomena in the engine while ensuring a high level of accuracy.

The AMICAL project focuses on advanced high-fidelity numerical techniques based on lattice Boltzmann and high-order Navier Stokes methods applied to industrial fan/outlet guide vane configuration to identify primary noise sources. The project will compute several fan/outlet guide vane configurations, including installation effects, noise reduction techniques, and wind tunnel experiments. The project will also focus on new post-processing techniques to improve noise source detection and comprehension.

Project Objectives

The AMICAL project aims at developing and validating advanced numerical tools, based on high-order and lattice Boltzmann methods, for the accurate and reliable prediction of UHBR aeroacoustic effects. A significant challenge of next-generation UHBR engines is noise reduction and it depends on high-fidelity simulation techniques at the pre-design stages. Developing innovative noise post-processing techniques is also part of the project objectives. New post-processing methodologies will be developed to exploit combined acoustic, numerical, and experimental databases to identify UHBR fan noise sources and improve the physical understanding of noise generation mechanisms.
