Larger wavelengths suit the hydrodynamics of carangiform swimmers
Muhammad Saif Ullah Khalid, Junshi Wang, Imran Akhtar +3
The wavelength of undulatory kinematics of fish is an important parameter to determine their hydrodynamic performance. This study focuses on numerical examination of this feature b…
Modal Decompositions of the Kinematics of Crevalle Jack and the Fluid-Caudal Fin Interaction
Muhammad Saif Ullah Khalid, Junshi Wang, Imran Akhtar +2
To understand the governing mechanisms of bio-inspired swimming has always been challenging due to intense interactions between the flexible bodies of natural aquatic species and w…
Flow Transitions and Mapping for Undulating Swimmers
Muhammad Saif Ullah Khalid, Junshi Wang, Haibo Dong +1
Natural swimmers usually perform undulations to propel themselves and perform a range of maneuvers. These include various biological species ranging from micro-sized organisms to l…
Adjoint-based optimization for thrust performance of a three-dimensional pitching-rolling plate
Min Xu, Mingjun Wei, Chengyu Li +1
An adjoint-based optimization is applied to study the thrust performance of a pitching-rolling ellipsoidal plate in a uniform stream at Reynolds number 100. To achieve the highest…
Vorticity dynamics of revolving wings: The role of planetary vortex tilting on the stability of the leading-edge vortex
Nathaniel H. Werner, Hojae Chung, Junshi Wang +4
This work investigated the vorticity dynamics and stability of leading-edge vortices (LEVs) in revolving wings. Previous studies suggested that Coriolis acceleration and spanwise f…
Optimized Body Deformation in Dragonfly Maneuvers
Ayodeji T. Bode-Oke, Samane Zeyghami, Haibo Dong
Tail bending associated with maneuvering flight of insects is a known phenomenon although there are only a few studies which analyze and quantify the effects and benefits of body c…
Study of turning takeoff maneuver in free-flying dragonflies: effect of dynamic coupling
Samane Zeyghami, Haibo Dong
Turning takeoff flights of several dragonflies were recorded during which a dragonfly takes off while changing the flight direction at the same time. Center of mass was elevated ab…
Coupling of the wings and the body dynamics enhances damselfly maneuverability
Samane Zeyghami, Haibo Dong
In flapping flight, motion of the wings through the air generates the majority of the force and torque that controls the body motion. On the other hand, it is not clear how much ef…
Flying with Abrupt Wing Flapping: Damselfly in Darting Flight
Chengyu Li, Haibo Dong, Wen Zhang
Damselflies show abrupt, darting flight, which is the envy of aero-engineers. This amazing ability is used both to capture prey and, by males, to establish territories that can att…
Unsteady Flow and Force Control in Butterfly Take-off Flight
Haibo Dong, Chengyu Li, Zongxian Liang +1
In this work, high-resolution, high-speed videos of a Monarch butterfly (Danaus plexippus) in take-off flight were obtained using a photogrammetry system. Using a 3D subdivision su…
Cicada: a Heavy but Agile Flyer
Kuo Gai, Yan Ren, Hui Wan +1
"Cicada: a Heavy but Agile Flyer" is a fluid dynamic video submitted to Gallery of Fluid Motion in APS-DFD 2011. Comparing to other insects, cicadas can generate much higher lift t…
Marching of Freely Falling Plates
Hui Wan, Haibo Dong, Zachary Gaston +1
"Marching of freely falling plates" is a fluid dynamics video for the Gallery of Fluid Motion submitted to APS-DFD 2011 at Baltimore Maryland. The problem of a freely falling plate…
Deterioration of Damselfly Flight Performance due to Wing Damage
Yan Ren, Zhe Ning, Kuo Gai +3
In this video, effect of chordwise damage on a damselfly (American Rubyspot)'s wings is investigated. High speed photogrammetry was used to collect the data of damselflies' flight…
An Integrated Study of Vortex Formation of Freely Flying Insects
Hui Wan, Yan Ren, Zongxian Liang +2
This is a short introduction illustrating movies submitted to "Fluid Dynamics Videos".
