PICS Colloquium: “Preserving microscale features in continuum models of fiber network materials”

Fiber networks at different length scales represent a prevalent microstructure of highly deformable materials and biological matter. At the microscale, these fiber networks are key for the function of biological systems, while at the macroscale they endow materials with striking characteristics, such as unusual kinematic behavior and high defect tolerance. Resolving the microstructure in discrete […]

PICS Colloquium: “Taking a layman’s perspective to turbulence modeling”

Abstract: Turbulence is an unsolved problem in classical physics. Its modeling often involves physical, mathematical, and numerical concepts that are daunting to even experienced engineers. This makes it very hard for a user to take a turbulence model from the literature and apply it in real-world engineering. This talk will take a layman’s perspective to […]

PICS Colloquium “Driving physics of inverted flag flapping”

Abstract: Fluid-structure interaction (FSI) is ubiquitous in the natural and engineered world, and a better understanding of FSI systems can aid in the design of renewable energy harvesting technologies, bio-inspired propulsion vehicles, and biomedical devices (to name a few applications). In this talk we will investigate “inverted” flag flapping, in which the flag is clamped at its […]

MEAM Seminar: “Continuum Mechanics of Non-equilibrium Phenomena: A Journey Through Space and Time Scales”

The fascinating diversity of material behavior at the macroscopic scale, including plasticity, phase transformations, viscoelasticity or diffusion, can only emerge from the underlying atomistic or particle behavior. Yet, the direct connection between these two scales for non-equilibrium phenomena remains an extremely challenging quest from both a theoretical and computational perspective. This knowledge gap currently hinders […]

PICS Colloquium: “Computational and Experimental Modeling of Membrane Distillation”

Abstract: Computational fluid dynamics simulations and experiments were conducted to study the performance of distillation membrane process for water treatment and desalination applications. Polarizations and fouling/scaling in a direct contact membrane distillation module were examined. Laminar and turbulent flow regimes in the feed and permeate channels were considered. The hydrophobic membrane separates feed and permeate […]

PICS Colloquium: “Molecular organization in biology: What can computer simulations teach us?”

Abstract: The formation of membraneless organelles (MLOs) via phase separation of proteins and nucleic acids has emerged as an essential process with which cells can maintain spatiotemporal control. Despite enormous progress in understanding the role of MLOs in biological function in the last ten years or so, the molecular details of the underlying phenomena are […]

PICS Colloquium: “From atoms to emergent mechanisms with information bottleneck and diffusion probabilistic models”

Abstract: The ability to rapidly learn from high-dimensional data to make reliable predictions about the future is crucial in many contexts. This could be a fly avoiding predators, or the retina processing terabytes of data guiding complex human actions. Modern day artificial intelligence (AI) aims to mimic this fidelity and has been successful in many domains […]

PICS Colloquium: “A model for external aerodynamics based on building-block flows”

Abstract: A wall model for large-eddy simulation is proposed by devising the flow as a collection of building blocks, whose information enables the prediction of the stress as the wall.  The core assumption of the model is that simple canonical flows (such as turbulent channel flows, boundary layers, pipes, ducts, speed bumps, etc) contain the […]

PICS Colloquium: “Kinetic theory for superparameterization of sea ice dynamics”

Arctic sea ice comprises of many ice floes whose dynamics is driven by oceanic/atmospheric currents and floe-floe interaction. Models of the effective sea ice dynamics  at large scales typically employ hydrodynamic equations of motion, such as mass and momentum conservation, with complex constitutive laws attempting to capture the rheology of sea ice as a continuum. Although hydrodynamic sea ice models […]
