Unsteady Aerodynamic Characteristics depending on Reduced Frequency for a Pitching NACA0012 Airfoil at Rec=2.3×10⁴
Autor: Jo Won Chang, Myong Hwan Sohn, Dong-Ha Kim
Publikováno v: International Journal of Aeronautical and Space Sciences. 18:8-16
Most of small air vehicles with moving wing fly at low Reynolds number condition and the reduced frequency of the moving wing ranges from 0.0 to 1.0. The physical phenomena over the wing dramatically vary with the reduced frequency. This study examin

Aerodynamic Features of Maple Seeds in the Autorotative Flight
Autor: Myong Hwan Sohn
Publikováno v: Journal of the Korean Society for Aeronautical & Space Sciences. 44:843-852
The autorotative flight of maple seeds(Acer palmatum) is numerically simulated based on the 3D geometry and the motion parameters of real seeds. The nominal values of the motion parameters are 1.26 m/s for descent velocity, 133.6 rad/s (1,276 rpm) fo

Effect of ambient medium viscosity on the motility and flagella motion of Prorocentrum minimum (Dinophyceae)
Autor: Kyung Won Seo, Seungmin Lim, Sang Joon Lee, Myong Hwan Sohn
Publikováno v: Journal of Plankton Research. 35:1294-1304
The effect of ambient medium viscosity on the motility and flagellar beating motion of the dinoflagellate Prorocentrum minimum was experimentally investigated. Prorocentrum minimum is a thecate desmokont dinoflagellate with two flagella that emerge f

Advances in digital holographic micro-PTV for analyzing microscale flows
Autor: Sang Joon Lee, Kyung-Won Seo, Myong-Hwan Sohn, Yong-Seok Choi
Publikováno v: Optics and Lasers in Engineering. 50:39-45
The accurate three-dimensional (3D) velocity field measurement technique has been receiving large attention in the study of microfluidics. DHM-PTV technique was developed by combining the digital holographic microscopy and particle tracking velocimet

Visualization and PIV study of wing-tip vortices for three different tip configurations
Autor: Myong Hwan Sohn, Jo Won Chang
Publikováno v: Aerospace Science and Technology. 16:40-46
The planform, profile, and cross-sectional views of the wing-tip region of a half-wing model with an aspect ratio of 3.2 and three different wing configurations, namely, square-cut, simple fairing, and Whitcombʼs full winglet wing-tip, were visualiz
