Evaluation of nacelle drag using computational fluid dynamics

Abstract: Thrust and drag components must be defined and properly accounted in order to estimate aircraft performance, and this hard task is particularty essential for propulsion system where drag components are functions of engine operating conditions. The present work describes a numerical method used to calculate the drag in different nacelles, long and short ducted. Two-and three-dimensional calculations were performed, solving the Reynolds Averaged Navier-Stokes (RANS) equations with a commercial Computational Flui… Show more

“…However, the cited study does not take into consideration the interaction between a nacelle and the pylon, wing, and fuselage. Work [5] reports results from modeling a flow around nacelle in the near and far fields. In contrast to paper [4], modeling accounted for the impact of the pylon, wing, and fuselage of an aircraft.…”
