“…Figure 5( a ) shows the distribution of the root mean square of the far-field pressure computed with the Ffowcs Williams–Hawkings analogy along a circumference centred at the slat cove with radius equal to 10 airfoil chords (Amaral et al. 2019). This figure indicates that the directivity pattern is very similar for both cases.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
