- RANS Turbulence / Transition Models: Extensions made to two-equation models for compressibility effects, density gradient effects, and non-linear effects. Scalar fluctuation model (SFM) developed to predict temperature/energy and species variance and dissipation - used to predict Prandtl-Schmidt number variations. Engineering Transitional model (ETM) developed which solves PDE's to predict transition onset and intermittency.
- AeroAcoustics/LES Modeling: Two equation k-epsilon models are being developed including: Explicit Algebraic Stress Models (EASM) to account for non-equilibrium effects
- Gas/Liquid Multiphase Problems: Development for multi-phase physics include dense sprays, high loading fluidized beds and cavitation in liquid rocket turbomachinery
- Hybrid Continuum/ DSMC Modeling: For flows containing both continuum and rarefied flow regions such as high altitude plume flows and re-entry flows
- Grid Adaptation/Error Control: For automated grid resolution and grid quality enhancement, as well as formal error quantification for solution verification using an error transport model
- Gas/Particle Combustion: Computational efficiency enhancement methodologies for acceleranting chemical kinetics, reduction of reaction mechanisms for complex fuels, and metallic nano-particle combustion
