The mechanics of many physical systems depends crucially on the interaction of flexible elastic structures with a fluid flow. Examples of macroscopic systems include the pumping of the heart in which blood flow interacts with valves, lift general in insect flight, and wave propagation in the cochlea of the inner ear. Examples of microscopic systems include the rheology of complex fluids and soft-matter which depends importantly on microstructures (such as colloids, lipids, polymers, vesicles) which interact with shear and extensional fluid flows serving through small-scale deformations to elastically store or dissipate energy. These microscopic processes often result macroscopically in material properties exhibiting interesting counter-intuitive phenomena and features hard to predict a priori. Immersed Boundary Methods (IBM) and Boundary Integral Methods (BIM) are numerical approaches for studying the mechanics of elastic structures which interact with a fluid.

Research Areas (Selected Subset for Highlights)

In the IBM formalism the hydrodynamic interactions of the composite system are handled by an approximate treatment of the fluid-structure stresses in which a Lagrangian representation of the immersed structures is coupled to an Eulerian representation of the fluid. In the BIM formalism the hydrodynamic equations are reduced to a description on the surface of an immersed structure usually taking the form of integral equations (possibly non-linear). The fluid-structure interaction problem and these underlying formulations present many interesting mathematical problems both for analysis and numerics.

Discussion of Above Items

Above is an experiment and rough draft / brainstorm. Idea is to give undergraduate / graduate students and general public and scientific audience sense of what types of work our group does. Above is meant to give an example of some themes and what we might post to highlight our specific research programs and on-going work both at the level of light-reading and in more detail. I wrote mostly about my own work, since I know the most about this activity presumably. :) I propose up-top we have short gallery style presentation of results for the light-of-heart. We then write in more detail a few of these short articles which discuss general thematic areas of research of the group (which of course can be modified over time to freshen things up and as our collective interests develop). This means people encounter what's new and light first, and then depending on their level of interest can scroll down for a more detailed desciption of the group.

Please take a shot at posting/editing the welcome message and some materials for discussion.

Above is an experiment and rough draft / brainstorm. Idea is to give newbie graduate students and general audience sense of what our group does. Above is meant to give an example of some themes and what we might post to highlight our specific research programs and on-going work. I wrote perhaps a little too much about myself, but this is since I know the most about this activity presumably. :) I propose we write several of these short articles which will be persistent for themes of the group (and modify over time as things develop). Up-top we then include some short descriptions of "fresh work" before these thematic short-articles. This means people encounter what's new first, but can scroll down for a more detailed view of our group.

Another model is not to have thematic articles, but to only have a few images up-top with a short caption and links to researchers webpages with more detailed info... [see UNC site].

Fluid-Structure Dynamics: Immersed Boundary Methods and Boundary Integral Methods

In the IBM formalism the hydrodynamic interactions of the composite system are handled by an approximate treatment of the fluid-structure stresses in which a Lagrangian representation of the immersed structures is coupled to an Eulerian representation of the fluid. In the BIM formalism the hydrodynamic equations are reduced to a description on the surface of an immersed structure usually taking the form of integral equations (possibly non-linear). The fluid-structure interaction problem and these underlying formulations present many interesting mathematical problems both for analysis and numerics. A common theme often arising in practice is that the resulting system of equations stiff as a consequence of fast time-scales introduced into the fluid-structure dynamics either by the elastic structures or in microscopic systems by thermal fluctuations. Several faculty members of the applied group work in this area both on analysis of fluid-structure systems and the development of efficient numerical methods.

Immersed Boundary Methods (IBM) and Boundary Integral Methods (BIM) are numerical approaches for studying the mechanics of elastic structures which interact with a fluid. Examples macroscopic systems include the pumping of the heart in which blood flow interacts with valves, lift general in insect flight, and wave propagation in the cochlea. In microscopic systems examples include the rheology of complex fluids and soft-matter which depends importantly on microstructures (such as colloids, lipids, polymers, vesicles) which interact with shear and extensional fluid flows serving through small-scale deformations to elastically store or dissipate energy. These microscopic processes often result macroscopically in material properties exhibiting interesting counter-intuitive phenomena and a priori hard to predict features.

Immersed Boundary Methods for Fluid-Structure Dynamics:

Immersed Boundary Methods (IBM) are numerical approaches for studying the mechanics of elastic structures which interact with a fluid. Immersed structures in IBM can be used to represent the mechanics of a variety of hydrodynamic systems from the macroscopic to microscopic. Examples include for macroscopic systems blood flow in the heart and interaction with valves, lift general in insect flight, and wave propagation in the cochlear. In microscopic systems examples include rheology of complex fluids / soft-matter as a results of microstructures interacting with fluid flows at small-scales where immersed structures represent solute particles, polymers, or membrane structures.

In the IBM formalism the hydrodynamic interactions of the composite system are handled by an approximate treatment of the fluid-structure stresses in which a Lagrangian representation of the immersed structures is coupled to an Eulerian representation of the fluid. Many interesting mathematical challenges arise both in the study of specific fluid-structure systems and in obtaining in general efficient numerical methods. In practice, fast time scales are often introduced into the fluid-structure dynamics by the elastic structures or in microscopic system by thermal fluctuations making the resulting system of equations stiff.

Faculty members working on fluid-structure problems include:

• Dr. Atzberger who has extended the IB methodology to include thermal fluctuations, by an appropriate stochastic forcing of the fluid-structure equations in accordance with the principles of statistical mechanics. Mathematically, the formalism is cast in terms of a system of Stochastic Partial Differential Equations (SPDE's). Uses results from stochastic calculus he has developed efficient stochastic numerical methods for the formalism. In collaboration with the Brown Group, Department of Chemistry, Dr. Atzberger's group is developing dynamic coarse-grained models of lipid bilayer membranes using the SIB formalism to account for molecular level interactions (lipid-lipid and lipid-solvent) along with hydrodynamic coupling and thermal fluctuations. For a more in-depth discussion see Dr. Atzberger's research website. A recent talk given by Dr. Atzberger on the Stochastic Immersed Boundary Method can be found here.
• Dr. Cinceros's who has recently formulated efficient implicit methods for the IBM formalisms significantly advancing the time-scales accessible in simulations of systems with stiff elastic structures...

Abstract: We study an all-to-all coupled network of identical excitatory integrate-and-fire (I\&F) neurons driven by an external spike train modeled as a Poisson process. Numerical simulations demonstrate that over a broad range of parameters, the network enters a synchronized state in which the neurons all fire together at regular intervals. We identify mechanisms leading to this synchronization for two regimes of the external driving current: superthreshold and subthreshold. In the former, a probabilistic argument similar to the proof of the Central Limit Theorem yields the oscillation period, while in the latter, this period is analyzed via an exit time calculation utilizing a diffusion approximation of the Kolmogorov forward equation. In both cases, stochastic fluctuations play a central role in determining the oscillation period. We also develop a criterion for synchrony in the network through a probabilistic argument. This work is in collaboration with Katherine Newhall, Gregor Kovacic, David Cai, and Aaditya Rangan.
