The article in the Journal of Fluid Mechanics introduces a new analytical model that combines linear unsteady aerofoil theory with inviscid actuator disc theory to predict the propulsive performance of oscillating foils. This model, which considers flow acceleration at the foil, shows improved agreement with large-eddy simulations. The study suggests that small-amplitude inviscid models can accurately forecast foil propulsion trends by accounting for local flow acceleration. The analytical solution from this model offers a quicker computational method compared to numerical panel solvers for assessing propulsive efficiency. The document includes the ORCID identifiers of authors Amanda S. M. Smyth, Takafumi Nishino, and Andhini N. Zurman-Nasution, as well as references to various studies on propulsive performance, flapping wing propulsion, wind turbines, and low-speed aerodynamics, providing a valuable resource for further research in fluid mechanics and aerodynamics.
