STAR-CD Physical Models

Not only does STAR-CD provide a rich source of models for turbulence, combustion, radiation and multiphase physics; it stands alone in offering all models on all mesh types. Furthermore, the end product is delivered within an ISO9001 accredited code development environment.

Flow regimes

• Steady and Transient, Laminar, Newtonian and non-Newtonian
• Turbulent (using a range of state-of-the-art turbulence models, including k-omega SST, V2f, LES and DES)
• Multiple frames of reference (flows in rotating machinery)
  
• Periodic flows, with and without heat transfer
• Unsteady flows caused by moving boundaries (e.g. for IC engine, mixers, stator/rotors)
• Incompressible and compressible (including transonic and supersonic)
• Hybrid wall functions removing near-wall Y+ constraints

Heat and mass transfer

• Heat transfer by convection (with buoyancy) and conduction (in solids and baffles)
  
• Radiation (including solar) in non-participating or participating fluid and solid media including discrete ordinates
  
• Mass transfer

Chemical reaction and combustion

• Multiple heterogeneous and homogeneous chemical reaction, including NOx
  
• Built-in algorithms to calculate chemical equilibrium compositions
• CHEMKIN and in-house complex chemistry solvers option with stiff chemistry capabilities
  
• Combustion of gaseous, liquid and solid (e.g.coal) fuels
• Special combustion capabilities for internal combustion engines (petrol and diesel)

Multiphase

• Distributed resistances (e.g. porous media, heat exchangers)
  
• Multiple fluid streams Lagrangian multiphase (dispersed gas/solid, gas/liquid, solid/liquid, liquid/liquid) with wall film deposits
  
• Eulerian two-phase flows
  
• Free surface modelling and cavitation

Multi-physics

• Aeroacoustics
  
• Fluid-structure interaction (three methods:
  integrated stress solver (v4.02), es-fsi, MpCCI)
