Dear Colleagues and Students,

The State Key Laboratory of Internet of Things for Smart City would like to invite you to join our “IOTSC Talk Series” on 03/02/2022 (Friday).
We are pleased to invite Prof. Lu JING from Shenzhen International Graduate School, Tsinghua University as the speaker.

Modeling Flows of Granular Materials: from Grain-Scale Mechanics to Continuum Models
Speaker: Prof. Lu JING, Assistant Professor, Shenzhen International Graduate School, Tsinghua University 
Date: 03/02/2022 (Friday)
Time: 11:00 – 12:00
Language: English
Venue: N21-5010 Meeting Room

Abstract:
Flow of granular materials lies at the heart of many geophysical processes and industrial activities. However, accurate modelling of granular flows remains a challenge due to the complex, multiscale behaviors of granular materials ranging from microscopic particle interactions to macroscopic continuum flows. In this talk, two common yet poorly understood aspects of granular flows are discussed: segregation and substrate slip. A multiscale paradigm is followed to tackle each problem by first identifying critical granular mechanisms at the grain level and then providing the associated closures for large-scale continuum modelling. These findings are expected to enhance physics-based granular flow modelling for various geophysical and industrial applications.

Speaker’s Bio:
Dr. Lu JING is Assistant Professor in the Institute for Ocean Engineering, Shenzhen International Graduate School, Tsinghua University. His research is focused on the fundamental mechanics of granular materials and granular-fluid mixtures, aiming to provide scientifically based solutions for geo-hazard mitigation and sediment management across fluvial, coastal, and marine environments. Dr. Jing is a member of TC105 “Geo-Mechanics from Micro to Macro” of the International Society for Soil Mechanics and Geotechnical Engineering. In 2021, he received an early career award from NSFC.
