Aerodynamic characteristics of flexible wings with leading-edge veins in pitch motions
Autor: YeongGyun Ryu, Jo Won Chang, Joon Chung
Publikováno v: Aerospace Science and Technology. 86:558-571
To demonstrate the effects of wing deformations on aerodynamic performances during the wing reversal, aerodynamic force/torque and flow vector-fields were measured. Wing models consisted of wing planes with various thicknesses and two leading-edge ve

Experimental investigation of flexible hawkmoth-like wings on the wing-wake interaction in hovering flight
Autor: Joon Chung, Dong-Ha Kim, YeongGyun Ryu, Jo Won Chang
Publikováno v: Journal of Bionic Engineering. 15:139-153
To study wing-wake interaction for various wing flexibilities, force measurements and digital particle image velocimetry were carried out on flapping hawkmoth-like wings in a water tank. Wing thickness was employed as a design variable for the wing f

Benefits of Intraoperative Continuous Renal Replacement Therapy During Liver Transplantation in Patients With Renal Dysfunction
Autor: Gyu-Sam Hwang, Seung Don Baek, Mun Jang, Sung-Gyu Lee, So Mi Kim, Hoon Yu, Sang-Hyun Hwang, Jo Won Chang, Won Young Kim, Eun Kyoung Lee
Publikováno v: Transplantation Proceedings. 49:1344-1350
Comparative outcomes of continuous renal replacement therapy during liver transplantation have not been investigated. We retrospectively compared the outcomes of intraoperative continuous renal replacement therapy with those of non-dialytic conservat

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

The advance ratio effect on the lift augmentations of an insect-like flapping wing in forward flight
Autor: Jong-Seob Han, Jo Won Chang, Jae-Hung Han
Publikováno v: Journal of Fluid Mechanics. 808:485-510
Time-varying force/moment measurements and digital particle image velocimetry (DPIV) were conducted to reveal the influence of an advance ratio$J$on an insect-like flapping wing. A scaled-up robotic model and a servo-driven towing tank were employed
