The Progress of KMA’s Impact-based Forecasting
Autor: Ji Ae Song, YoungYoung Park, Wonho Kim, Yeongseon Kim, Yongjun Ahn, Ji-Hyeon Kim, Hyojin Han, KyongJun Lee
The Korea Meteorological Administration (KMA) set a main policy goal as “Impact-based forecasting (IBF) for mitigation of meteorological disaster risks” in 2016. As a first step toward the goal, each regional office of the KMA operated a prototyp

Development of a Cartesian-based Code for Effective Simulation of Flow Around a Marine Structure - Integration of AMR, VOF, IBM, VIV, LES
Autor: Kyongjun Lee, Kyung-Soo Yang
Publikováno v: Journal of the Society of Naval Architects of Korea. 51:409-418
Simulation of flow past a complex marine structure requires a fine resolution in the vicinity of the structure, whereas a coarse resolution is enough far away from it. Therefore, a lot of grid cells may be wasted, when a simple Cartesian grid system

EFFECTS OF ROUNDING CORNERS ON THE FLOW PAST A SQUARE CYLINDER
Autor: Doohyun Park, Kyung-Soo Yang, Changwoo Kang, Kyongjun Lee
Publikováno v: Journal of computational fluids engineering. 19:57-63
This study performed numerical analysis for the characteristics of flow-induced forces and the flow instability depending on the cross-sectional shape of the cylinder in laminar flow. To implement the cylinder cross-section, we adopted an Immersed Bo

CHANGE OF CHANNEL-FLOW TOPOLOGY BY A STREAMWISE-PERIODIC ARRAY OF ROTATING CIRCULAR CYLINDERS
Autor: Taekyeong Jeong, Kyung-Soo Yang, Chang-Woo Kang, Kyongjun Lee
Publikováno v: Journal of computational fluids engineering. 18:17-24
In this study, we consider the characteristics of channel flow in the presence of an infinite streamwise array of equispaced identical rotating circular cylinders. This flow configuration can be regarded as a model representing a micro channel or an

Flow instability in obstructed channel flow
Autor: Kyongjun Lee, Kyung-Soo Yang
Publikováno v: Computers & Fluids. 84:301-314
Flow instability in a channel obstructed by an infinite array of equi-spaced circular cylinders has been numerically studied. An immersed boundary method was employed to facilitate the placement of the cylinders within a Cartesian grid system. This f

HEAT TRANSFER ENHANCEMENT IN CHANNEL FLOW BY A STREAMWISE-PERIODIC ARRAY OF CIRCULAR CYLINDERS
Autor: Changwoo Kang, Kyongjun Lee, Kyung-Soo Yang, Taekyeong Jeong
Publikováno v: Journal of computational fluids engineering. 18:85-92
In this study, we consider heat transfer enhancement in laminar channel flow by means of an infinite streamwise array of equispaced identical circular cylinders. This flow configuration can be regarded as a model representing a micro channel or an in
