title = "Computational assessment of actuator line model for large eddy simulation of rotor noise",
abstract = "A hybrid Large Eddy Simulation (LES) / Actuator Line Model (ALM) approach is employed to simulate the flow generated by the 2-bladed Knight-Hefner rotor in hover [1]. LES / ALM predictions are compared to previously performed LES using the Immersed Boundary Method (IBM) to handle the rotating blades. The previous LES / IBM were validated against measured data for Figure of Merit and to hybrid RANS / LES predictions obtained using the Helios code [2]. Finally, the impact of the LES / ALM approach for complex UAV rotor noise is assessed using the Ffowcs-Williams Hawking (FWH) acoustic analogy method. Predictions of rotor flow and noise using the LES / ALM will be compared to published PIV and noise measurements [3, 4].",
