Talk One

Title: Introduction to Chaos and Nonlinear Science

Abstract:

The study of linear mathematical and physical systems still contains many open problems but is otherwise quite well developed. Since the second half of the 20th Century mathematicians, physicists and engineers have been attracted to the study of nonlinear systems and made tremendous progress. This development is being continued and has constituted one of the forefronts of science of the 21st Century. Nonlinear systems have many interesting, and sometimes peculiar behaviors such as periodicity, bifurcations, pattern formations, chaos, turbulence, self-regulation, self-organization, self-assembly, etc. In this talk, the speaker will give a heuristic introduction about such nonlinear responses and behaviors to the audience. No prerequisite is required.

Talk Two

Title: Mathematical and Computational Study of Wind Energy

Abstract:

Wind energy is a principal form of renewable energy being actively developed by many nations in the world. The model of wind turbine flow is  based on the Navier-Stokes equation with rotational dynamics, which is rather challenging to analyze mathematically. Thus, much of any useful study must be done via computational mechanics involving large-scale scientific computation. In this talk, the speaker will first give some overviews of wind energy development, and then present his study of some issues of interest from a  mathematical perspective. In particular, he will present recent numerical results and visulization obtained by his group at Texas A&M University and Texas A&M University-Qatar computed by using the OpenFOAM software, leading to an improved understanding of wind-turbine flows and wind farm layout designs.
