00925njm 22002777a 4500 dc Arias Montenegro, Francisco Javier author 2021-01-12 Ferrofluid moving thin films and their possible significance with regard to active flow control for lift and attack angle enhancement are discussed. In this strategy, a very thin film of ferrofluid is strongly attached at the wall of the wing by a normal magnetic field from below and pumped tangentially along the wing. Utilizing a simplified physical model and from the available experimental data on moving walls, the expected lift enhancement and effect on the attack angle were assessed. Additional research and design is required in order to explore the possibilities in the use of ferrofluid moving thin films This research was supported by the Spanish Ministry of Economy and Competitiveness under fellowship grant Ramon y Cajal: RYC-2013-13459 Postprint (author's final draft) Àrees temàtiques de la UPC::Enginyeria mecànica::Mecànica de fluids Àrees temàtiques de la UPC::Aeronàutica i espai::Aerodinàmica Airplanes -- Wings Surface active agents Fluid dynamics Ferrofluid Boundary layer separation Active flow control Avions -- Ales Avions -- Materials Agents tensioactius Dinàmica de fluids Ferrofluid moving thin films for active flow control
