Abstract

This paper highlights the link between the unsteady aerodynamics and Open Fan tonal noise generation prediction using the hybrid computational methodology combining the unsteady Reynolds Averaged Navier-Stokes (uRANS) simulation with Ffowcs-Williams and Hawkings (FWH) acoustic analogy. Among the var...
