Blade Design and Aerodynamic Performance Analysis of a 20 MW Wind Turbine for LCoE Reduction
Autor: Kang-Ho Jang, Ki-Wahn Ryu
Publikováno v: Energies, Vol 16, Iss 13, p 5169 (2023)
The aim of this study is to develop a blade mass model that incorporates a low-induction rotor (LIR) and a low-specific power concept to reduce aerodynamic loads and lower the Levelized Cost of Energy (LCoE). This blade mass model replaces the tradit

Evidence of Long-Distance Droplet Transmission of SARS-CoV-2 by Direct Air Flow in a Restaurant in Korea
Autor: Young Joon Park, Don Myung Jung, Ki Wahn Ryu, Ju-Hyung Lee, Jung Im Park, Keun Sang Kwon
Publikováno v: Journal of Korean Medical Science
Background The transmission mode of severe acute respiratory syndrome coronavirus 2 is primarily known as droplet transmission. However, a recent argument has emerged about the possibility of airborne transmission. On June 17, there was a coronavirus

Reynolds Number Extrapolation on High Thickness-Ratio Airfoil for Megawatt-Class Wind Turbine
Autor: Ki-Wahn Ryu, Sung Cheoul Roh, Seung-Hee Kang
Publikováno v: International Journal of Aeronautical and Space Sciences. 19:575-583
A Reynolds number extrapolation method of determining aerodynamic loads acquired from a wind tunnel test on high thickness-ratio airfoils usually adopted in a megawatt-class wind turbine blade was investigated to obtain equivalent results to those of

Wear Depth Prediction for Steam Generator Tubes Using an Estimated In Situ Wear Coefficient
Autor: Ki-Wahn Ryu, Chi-Yong Park, Huinam Rhee
Publikováno v: Nuclear Technology. 201:23-40
This study proposes a methodology to estimate time-varying in situ wear coefficient between steam generator tubes in nuclear power plants and their supporting structures. Actual wear depth measurement data of steam generator tubes of OPR1000 (Optimiz

Hydrodynamic Cause Analysis for Roof Damage on Water Storage Tank
Autor: Ki-Wahn Ryu
Publikováno v: Journal of Pressure Vessel Technology. 142
The causes of roof damage found on a large-scale water storage tank were investigated using hydrodynamic analysis. All operation and weather data, such as temperature inside and outside of the storage tank, atmospheric pressure, water level according
