The discrete element method (DEM) is a powerful simulation tool that provides the details of the flow of individual particles and facilitates quick parametric studies, eliminating the need for expensive experimental testing. This presentation will outline advances in DEM to simulate the motion of cohesive and/or aspherical particles. Aspherical grains are described either as perfect cylinders or disks of varying aspect ratio or described using a linked and overlapping sphere approach. Using this linked approach, the flow of flexible aspherical particles can also be treated via a bonded particle model that incorporates normal and shear forces as well as bending and torsional moments. The bonded particle model also allows for breakage of aspherical particles during impact. Cohesion between particles is described as originating either from surface moisture, described by a liquid bridge force model in the case of pendular liquid bridges, or from van der Waals interactions, described by the adhesive JKR model. DEM simulations are validated via experiments of hopper flow/discharge and measurements of particle-phase stress in a ring shear cell.

"Tackling Complex Flow Problems via Numerical Simulation: From Jumping Fish and Heart Valves to River Flooding and Wind Energy" – November 22, 2019

Dean Fotus Sotiropoulos

View Presentation Slides (coming soon)

Fotis Sotiropoulos serves as Dean of the College of Engineering and Applied Sciences and SUNY Distinguished Professor of Civil Engineering at Stony Brook University. Before joining Stony Brook, he was the James L. Record Professor of Civil Engineering; Director of the St. Anthony Falls Laboratory; and Director of the EOLOS wind energy research consortium at the University of Minnesota, Twin Cities (2006-2015). Prior to that, he was on the faculty of the School of Civil and Environmental Engineering at the Georgia Institute of Technology, with a joint appointment in the G. W. Woodruff School of Mechanical Engineering (1995-2005).  His research focuses on simulation-based engineering science for tackling complex, societally relevant fluid mechanics problems in energy, environment and human-health applications. He has authored more than 190 peer-reviewed journal papers and book chapters and his research results have been featured on the cover of several prestigious journals. His laurels include the 2019 American Geophysical Union (AGU) Hydrology Days Borland Lecture in Hydraulics, the 2017 Hunter Rouse Hydraulic Engineering Award from the American Society of Civil Engineers (ASCE), a 2014 distinguished lecture of the Mortimer and Raymond Sackler Institute of Advanced Studies at Tel Aviv University, and a CAREER Award from the National Science Foundation.  Sotiropoulos is a Fellow of the American Physical Society (APS) and the American Society of Mechanical Engineers (ASME) and has twice won the APS Division of Fluid Dynamics Gallery of Fluid Motion (2009, 2011).

The fluid mechanics problems at the center of many of these challenges are often so complex that simulation-based research is the only viable approach for tackling them. Examples range from disease-promoting blood-flow patterns in the human heart and bio-inspired swimming robots to extreme flooding in waterways and harnessing renewable energy from wind, currents, and waves. Accurate numerical simulation of such flows poses a formidable challenge to even the most advanced computational methods available today. Dean Sotiropoulos will discuss the advances he has made in developing a powerful computational framework, the Virtual Flow Simulator (VFS), which can: handle arbitrarily complex geometries encountered in real-life applications; simulate fluid-structure interaction for rigid and flexible bodies; account for two-phase flows and free surface effects; and carry out coherent-structure-resolving simulations of turbulent flows in arbitrarily complex domains with dynamically evolving boundaries. The ability of the method to yield striking new insights into the physics of a broad range of real-life problems will be demonstrated by discussing applications in aquatic biology, cardiovascular engineering, turbulence and transport processes in natural waterways, and wind and marine and hydrokinetic energy. He will also touch upon future grand challenges and opportunities for simulation-based fluid mechanics research.

Martin E. Hellman

Professor Emeritus of Electrical Engineering, Stanford University
"The Evolution of Public Key Cryptography" – October 23, 2018

Martin Hellman is best known for inventing public key cryptography, the technology that enables secure Internet transactions. He also has contributed to the computer privacy debate and was a key participant in the “first crypto war” of the late 1970s. He has authored over seventy technical papers, twelve US patents and a number of foreign equivalents. His many honors include election to the National Academy of Engineering and receiving (jointly with his colleague Whit Diffie) the million dollar ACM Turing Award, the top prize in computer science.

While public key cryptography is seen as revolutionary, after this talk you might wonder why it took Whit Diffie, Ralph Merkle and Hellman so long to discover it. This talk also highlights the contributions of some unsung (or “under-sung”) heroes: Ralph Merkle, John Gill, Stephen Pohlig, Richard Schroeppel, Loren Kohnfelder, and researchers at GCHQ (Ellis, Cocks, and Williamson).
