“Phase Field Modeling of Interfacial Phenomena”
Guest Speaker: Dr Arnoldo Badillo
Abstract
Although we might not be fully aware of the presence of interfaces in our daily lives, they play a fundamental role in our modern society. From the generation of electricity in power stations, to the way we manufacture cars, produce electronic devices, and how we cook our food. Interfaces are everywhere, and a deeper understanding of them, will lead the way to the development of new technology to achieve a sustainable society. To enter the realm of interfacial matter, we must first answer two questions: What is an interface? How do we model them? In this seminar, I will address these two questions from an atomistic view point, and then I will introduce the Phase Field formalism to model the dynamic evolution of interfaces. I will finish this talk presenting a quantitative comparison between Phase Field predictions and experimental results for evaporation and wetting phenomena.

Biography
Dr Arnoldo Badillo is a Research and Development Engineer at Alfa Romeo Racing, the Swiss team competing in Formula 1. He holds a Master’s degree in Mechanical Engineering and a PhD in Materials Science from the University of Santiago (Chile). In 2003, he moved to the USA to work as Postdoctoral Research Scholar at the University of Iowa, where he carried out experimental and theoretical work in the field of crystal growth. He continued his theoretical and applied research at the Department of Materials Science and Engineering at the University of Illinois at Urbana-Champaign. There, he developed a novel Phase Field model for predicting microstructural evolution of metallic alloys under sustained irradiation of energetic particles. From 2008 until 2016, he served as Scientific Officer at the Paul Scherrer Institute in Switzerland, where he worked on Phase Field modeling of multiphase turbulent flows, wetting phenomena, solidification, and Uncertainty Quantification in Computational Fluid Dynamics.
