Computational Aeroacoustics (CAA) is a field of study that uses numerical methods to simulate and predict the generation, propagation, and effects of sound waves in a fluid flow. This category can include the analysis of noise generated by aircraft, wind turbines, and other machinery that operate in a fluid environment. The goal of this category CAA is to improve the understanding of the physical processes that lead to sound generation and to develop new technologies and design methods that can reduce noise emissions and improve overall performance. The discussion group is focused on the latest advancements, challenges, and future directions in the field of Computational Aeroacoustics.
