On the applicability of the actuator line method for unsteady aerodynamics
Elías Alva, Vitor G. Kleine, André V. G. Cavalieri
A linear theory for unsteady aerodynamic effects of the actuator line method (ALM) was developed. This theory is validated using two-dimensional ALM simulations, where we compute t…
Airfoil tonal noise reduction by roughness elements Part I -- Experimental investigation
Elías Alva, Zhenyang Yuan, Tiago B. Araújo +3
Laminar separation bubbles around airfoils lead to the growth of instability waves, which enhances to acoustic scattering at the trailing-edge, forming a feedback loop that produce…
Airfoil Tonal Noise Reduction by Roughness Elements. Part II -- Direct Simulations
Zhenyang Yuan, Elías Alva, Tiago B. de Araújo +2
In a combined experimental and numerical effort we investigate airfoil tonal noise generation and reduction. The means of noise control are streak generators in form of cylindrical…
