Turbulence and Flow Control Laboratory
난류 및 유동 제어 연구실
Turbulence is a ubiquitous phenomenon in environmental and engineering flows. Turbulent flows enhance the transport and mixing of momentum, heat, or matter and also lead to the large wall-shear stress near solid walls. Consequently, turbulent flows have an essential role in predicting meteorological phenomena and in designing many engineering applications (e.g., submarines, ships, aircraft, pipelines, heat exchangers, etc.). However, understanding turbulent flows is a long-standing challenge due to the complex, chaotic, and multi-scale nature of turbulence. We study coherent structures or eddies that are crucial to understanding the multi-scale phenomena of turbulence, especially for high-Reynolds-number flows.
TFC Lab focuses on 1) investigating the coherent structures that characterize the high-Reynolds-number phenomena and the fundamental law of wall turbulence, 2) establishing the sustaining mechanism of turbulence based on the dynamics of the coherent structures, 3) proposing a new prediction model in complex engineering systems and a flow control systems with less environmental impacts.
난류 및 유동 제어 연구실에서는 1) 고 레이놀즈수 난류 유동 및 기본적인 난류 법칙과 관련된 응집 구조를 연구하고, 2) 응집 구조 역학 분석을 바탕으로 난류 유지 메커니즘을 규명하여, 3) 복잡한 공학시스템에 적용 가능한 유동 예측 모델 및 유동 제어 기법에 대한 새로운 비전을 제시하는 것을 목표로 한다.
We are currently recruiting undergraduate and graduate students to work on a number of exciting research.
