Technical Note: Simulation of Tiltrotor Fountain Flow Field Effects Using a Finite Volume Technique — An Aero‐Acoustic Study
Abstract:This paper presents the results from an aero‐acoustics analysis for a tiltrotor obtained by coupling an efficient Navier‐Stokes solver, RO'ITILT, with the acoustic code WOPWOP. The flow solver is finite volume based and solves the three dimensional, steady, laminar, incompressible equations in Cartesian coordinales. The acoustic code WOPWOP is an implementation of Farassat's linearized formulation 1A. Predicted and measured fountain velocities are presented for a 15 percent
