About this event

Professor Wooyoung Choi (New Jersey Institute of Technology, USA) will be visiting Loughborough University from 17 to 23 June 2018. The visit is supported by the Institute of Advanced Studies. He will give an Open Lecture entitled:

Nonlinear waves and their interactions in the ocean

on Friday, 22 June, 18.00 - 19.00 in SCH001.

Wooyoung Choi is a Professor in the Department of Mathematical Sciences at the New Jersey Institute of Technology (NJIT) in the USA. He received the B.S. and M.S. degrees from the Seoul National University, Korea, in 1980 and 1984, respectively, and the Ph.D. degree in engineering science from Caltech, USA, in 1993.  Before he joined NJIT, he was with the Los Alamos National Laboratory and the University of Michigan. Recently he visited the Korea Advanced Institute of Technology (KAIST) in Korea for 5 years as an WCU (World Class University) visiting professor. His main current research interests lie in hydrodynamics and scientific computing with the focus on nonlinear waves and geophysical flows. 

Abstract

Nonlinear wave phenomena in the ocean are ubiquitous both on its surface and in its interior. Nevertheless, as the wave motions are often highly nonlinear and their spatial scales range from millimeters to thousands of kilometers, it is a nontrivial task to accurately model their generation, propagation, and dissipation. It is even more challenging when complicated interactions occur among waves of different spatial scales. In this talk, I will present recent efforts to better understand the underlying physics  of highly nonlinear waves in the ocean through combined theoretical and experimental investigations and to develop reliable mathematical models to represent the evolution of such waves. Starting with surface waves possibly in the presence of external forcing and energy dissipation due to wave breaking, I will describe nonlinear internal waves in density-stratified oceans and their interactions with surface waves. Then, some remaining challenges and open questions will be discussed.
