Title: Exponential Time Differencing for Solving Phase-Field Equation

Keynote Speaker: Qiao Zhonghua

Abstract:

Exponential time difference (ETD) is a kind of highly efficient time discretization method for studying differential equations. Based on the time integral construction approximation scheme of exponential integral factor, ETD includes multi-step method and Runge-Kutta (RK) method. Refer to the literature review for a more complete discussion and analysis of ETD schemes [M. Hochbruck and A. Ostermann. Exponential Integrators. Acta Numer., 19:209-286, 2010]. Only several ETD schemes and their applications in the numerical calculation of phase-field model.

Introduction to the Speaker:

Dr. Qiao Zhonghua received his doctoral degree from Hong Kong Baptist University, and is now an Associate Professor of Department of Applied Mathematics, The Hong Kong Polytechnic University. Before joining the Department of Applied Mathematics, The Hong Kong Polytechnic University, Dr. Qiao once acted as the Assistant Professor of Department of Mathematics, Hong Kong Baptist University from August 2008 to December 2011, and was engaged in post-doctoral research in the Center for Computational Science and Engineering of North Carolina State University from July 2006 to July 2008.

Dr. Qiao is mainly engaged in the algorithm design and analysis of numerical differential equations. In recent years, he focuses on the research on the numerical simulation of phase-field equations and the efficient algorithm for computational fluid dynamics. So far, he has published over 50 papers in SCI journals, and his articles have been cumulatively cited more than 800 times. He was awarded the 2013-2014 Distinguished Young Scholar Award by Hong Kong Research Grants Council in 2013, the Young Scholar Award of Hong Kong Mathematical Society in 2018, and the conferred the title of research scholar of Hong Kong Research Grants Council in 2020.
