Dynamic stall of an aerofoil in ramp-up motion

Dynamic stall of an aerofoil in ramp-up motion Marco Edoardo Rosti, City University of London Mohammad Omidyeganeh, City University of London Alfredo Pinelli, City University of London DOI: We have studied the three dimensional, unsteady, flows around a wing in various flight conditions, mimicking those experienced during take-off and landing or the influence of a wind gust. With the aid of numerical simulations, as an alternative to experiments in wind tunnel, we were able to develop new wing designs that can enhance aerodynamic performance at no extra cost. These can improve an aircraft’s maneuverability, increase the amount of weight it can carry, or reduce the fuel consumed – all of which may contribute to reductions in greenhouse gases.
