Suppression of vortex shedding inspired by a low-dimensional model
, 2000 In this paper, we show by two-dimensional numerical simulation that it is possible to control vortex shedding behind a circular cylinder by inserting two small vortex perturbations in the flow.

Quasimolecular channel and vortex street modeling on a supercomputer
, 1988 A quasimolecular model is developed for the simulation of vortex development in prototype fluid flow problems. The approach is formulated mathematically as an n-body problem which incorporates classical molecular type forces.

How do You Map a Von Karman Vortex Street and How do You Use One to Generate Electricity?
, 2018 Swirling structures in calmly flowing water inspire a deep, primal sense of peace and well-being. At the same time, images of Poe’s maelstrom in turbulent oceans inspire a sense of terror.1 Throughout the duration of my PhD, modelling the flow through ...

Influence of the Francis turbine stay vane trailing edge shape on generation of Karman vortex street
, 2015 In the flow past bluff bodies for a certain range of velocity a periodical vortex shedding emerges which is known as von Kármán vortex street. This phenomenon causes the periodical alteration of pressure field which affects the body.

WRF 모델을 이용한 Karman Vortex Street의 재현과 위성 패턴 비교 연구
, 2013 Karman Vortex Street (KVS)는 인공위성 이미지의 구름 패턴에서 쉽게 확인할 수 있다. 본 연구에서는 제주도 남부 해역의 KVS에 대해 WRF 모델을 이용하여 재현하고, 이에 가장 적합한 파라미터를 추출한다. WRF 모델의 Planetary Boundary Layer (PLB) 물리과정에 따른 바람자료를 산출하였으며, 이를 이용하여 제주도 남부 해역의 KVS를 재현하였다.
