International Conference on Model Integration across Disparate Scales in Complex Turbulent Flow Simulation (ICMIDS)

This specialized meeting focuses on the growing importance of complex flows that couple multiple turbulence dynamical systems over disparate ranges of length and time scales. The combined modeling, algorithmic, numerical and dynamical complexities within high performance computing (HPC) environments have created major challenges that will be addressed in this focused meeting of researchers who wish to exchange experiences, discuss challenges and develop solutions for future advancement. Together with HPC complexity is complexity of measurement and its integration with simulation to advance knowledge and for computational validation.

ICMIDS will comprise invited, podium and poster presentations and discussion forums: 

  • Technical and poster presentations focused on multiscale turbulence simulation and model integration with a focus on:
    • New ideas, methods and insights with recent and developing research.
    • Integration of physics, modeling, numerics, gridding, simulation and data management and analysis.
    • Communication between experiment and simulation with focus on physics.
  • Invited perspective presentations from leaders in turbulence modeling, numerical methods for turbulence simulation, and experimental fluid dynamics specific to the complexity theme of the meeting.
  • Poster presentations focused on applications with modern computational, modeling and/or experimental methods.

The following topics are of particular interest for this conference:

  • Modeling the interfaces between surface viscous layers and outer turbulent flow regions in wall-bounded turbulent flows (e.g., hybrid URANS-LES, Scale Adaptive Simulation (SAS) methods, contrasting "pure URANS" and "hybrid URANS-LES")
  • Fundamental distinctions among "RANS-like," "URANS-like," and "LES-like" models; challenges to coupling between disparate model classes.
  • The physics of forced non-stationary nonequilibrium high Reynolds number boundary layer flows, including nonsteady boundary layer separation and transition.
  • Simulation of meso-micro scale couplings in geophysical turbulent flows including meso-scale data assimilation. Models for unsteady turbulent inflow boundary conditions.
  • Surface flux models (momentum, heat, etc.) when the surface viscous layer(s) cannot be resolved or do not exist due to roughness, and special difficulties associated with lack of horizontal homogeneity and/or non-planar topography.
  • Modeling the interactions between large-scale unsteady spatially varying turbulent environments and small-scale high Reynolds number boundary dynamics and engineered systems (e.g., interactions between atmospheric or oceanic turbulence and utility-scale wind turbines, water turbines, aircraft and maritime vessels).
  • Interactions between the ocean surface and internal waves, with high-Reynolds number small-scale turbulence in mid-water and in ocean bottom boundary layers.
  • Transport and mixing in highly anisotropic stratified turbulence, especially at high Reynolds numbers where it is often assumed that stratification suppresses turbulence).
  • Turbulent fluxes of biogeochemical constituents, and particulate transport and resuspension, across sediment-water interfaces and sea-bed boundary layers.
  • Field and laboratory experiments on the couplings among complex nonstationary disparate turbulence scales for physical insight and model validation and on near-surface dynamics relevant to surface models.

This symposium is specifically directed at new developments for the integration of models across disparate scales coupled with grid, algorithmic and numerical requirements and at fundamental physics underlying dynamical interactions across disparate scales in complex turbulent flows. We seek a balance and strong discourse between experiment and simulation and between dynamical complexity, modeling simplification, and limitations associated with grid, algorithm and boundary conditions.

The organizers are particularly supportive of, and encourage attendance and abstract submission by individuals in groups underrepresented in science and engineering (e.g., underrepresented minorities, women, and persons with disabilities). The organizers are not able to provide child care and other types of family care at the conference site under the purview of the Pennsylvania State University. However such arrangements can be made by contacting the local conference organizer, Robert Kunz,, 814-260-1901.

There will be no published manuscripts; all presentations will be made available to participants electronically immediately after the conference. The conference will be located at Penn State University. Convenient and comfortable lodging is available very close to the conference venue accessible by foot. We will host a banquet on day 2 at the lovely Presidents Suite at Beaver Stadium. State College is located in the beautiful Allegheny Mountains of central Pennsylvania and is easily accessible by air and by car from near-by metropolitan areas such as Washington D.C., New York, Philadelphia and Pittsburgh.
