Perfect combination of lightness and ingenuity: secrets in the flight of Paratuposa placentis
-
Abstract: By using experimental approach, three-dimensional morphological and kinematic models for the flight of Paratuposa placentis are reconstructed. The secrets in the high-performance flight of Paratuposa placentis are successfully unveiled through computational fluid dynamics (CFD) analysis.
