Author De Oliveira Andrade, G.L. (TU Delft Wind Energy) Balbino dos Santos Pereira, R. (TU Delft Wind Energy) Ragni, D. (TU Delft Wind Energy) Avallone, F. (TU Delft Wind Energy) van Bussel, G.J.W. (TU Delft Wind Energy) Date 2016 Abstract The article seeks to unify the treatment of conservative force interactions between axi-symmetric bodies and actuators in inviscid ow. Applications include the study of hub interference, di_user augmented wind turbines and boundary layer ingestion propeller con_gurations. The conservation equations are integrated over in_nitesimal streamtubes to obtain an exact momentum model contemplating the interaction between an actuator and a nearby body. No assumptions on the shape or topology of the body are made besides (axi)symmetry. Laws are derived for the thrust coe_cient, power coe_cient and propulsive e_ciency. The proposed methodology is articulated with previous e_orts and validated against the numerical predictions of a planar vorticity equation solver. Very good agreement is obtained between the analytical and numerical methods To reference this document use: http://resolver.tudelft.nl/uuid:84f8d77a-4fda-462c-9aa0-03d7fd12f608 DOI https://doi.org/10.1088/1742-6596/753/2/022005 ISSN 1742-6588 Source Journal of Physics: Conference Series, 753 Event TORQUE 2016: 6th International Conference "The Science of Making Torque from Wind", 2016-10-05 → 2016-10-07, Technische Universität München (TUM), Campus Garching, Munich, Germany Part of collection Institutional Repository Document type journal article Rights © 2016 G.L.
