Web30 mrt. 2024 · Abstract. This paper presents a novel method for airfoil drag estimation at Reynolds numbers between 4 × 10 5 and 4 × 10 6. The novel method is based on a systematic study of 40 airfoils applying over 600 numerical simulations and considering natural transition. The influence of the airfoil thickness-to-chord ratio, camber, and … Webfinement was used to resolve flow behind the airfoil more ac-curately. As can be seen in Figure 5 (b), prismatic layer was added to the area around the airfoil to enable more accurate fit of the wall function. Figure 4: Computational grid. Figure 5: a) mesh around airfoil, b) prismatic layer.
