What is it about?
Comparison between two fidelity approaches: High (by OpenFOAM) and Mid (by DUST) in terms of their prediction of performance and acoustics of a single isolated eVTOL rotor. The results are validated against experimental data, taken by a partnered research group.

Why is it important?
It allows to optimize the early stage of the rotor design by using mid-fidelity tool and get accurate results to a reasonable extent.
Perspectives
As a researcher continuously navigating the complexities of computational fluid dynamics and aeroacoustic modeling, the computational bottleneck of high-fidelity simulations is a daily reality. This publication was driven by the practical need to accelerate the Urban Air Mobility (UAM) design cycle. While high-fidelity tools like OpenFOAM provide unparalleled physical insight into unsteady wake dynamics and broadband noise , the reality of requiring nearly a month of supercomputing time to resolve a single second of physical flight makes them impractical for early-stage iteration.
