Computational Capabilities

Framework for all Mach number, multi-species, turbulent reacting flow at standard, trans-critical and supercritical conditions
  • Thermodynamic properties: standard, trans-critical and supercritical conditions
  • Turbulence models: Large eddy simulation (LES) (algebraic and dynamic Smagorinsky model), Detached eddy simulation (DES), Mentor's k-omega SST two-equation model, Baldwin-Lomax algebraic model, Spalart-Allmas one equation model
  • Turbulence-chemistry interactions: Steady Flamelet approach, extended Flamelet-Progress-Variable method and finite rate direct closure
  • Numerical scheme: up to fourth order accurate in space and second order in time, with scalar or matrix artificial dissipation to assure TVD properties, all Mach number with pre-conditioning scheme for steady and unsteady flows
  • Parallelization: Multi-block structured grid based on MPI
  • Lagrangian spray modeling
Framework for multiphase interfacial flows
  • Time-dependent incompressible variable-density Navier-Stokes equations
  • Adaptive mesh refinement (AMR): resolution is adapted dynamically
  • Advected/diffused passive tracers and additional source terms
  • Volume of Fluid (VOF)advection scheme for interfacial flows, with accurate treatment of surface tension
  • Multiphase electrohydrodynamics
Data analysis and design framework (based on DNS and LES data)
  • Design of experiments
  • Uncertainty quantification
  • Reduced order model development
  • Surrogate modeling based on machine learning techniques
Hardware Infrastructure
  • 800 Intel Xeon 6148 processors
  • 192 GB RAM/core
  • Omni-Path communication architecture (100 Gb/s switch)
  • Multiple graphics workstations for visualization
