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…
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…
