STAR-CD Physical models

Comprehensive CFD Functionality
STAR-CD Solver는 Turbulence, Combustion, Radiation 및 Multiphase에 대한 많은 모델을 제공할
뿐만 아니라 산업용 CFD Code에서 제공하는 모든 모델 및 격자 종류를 지원합니다. 이는 CD-adapco의
“one code” 철학에 따른 결과입니다. 게다가 이는 ISO9001:2000의 인증을 받은 Code 개발환경 내에서
제작되고 있습니다.

Covered Flow Regimes and Conditions
 - Steady and transient, laminar Newtonian and non-Newtonian flows
 - Turbulent flows
    (using a variety of state-of-the-art turbulence models, including LES and DES)
 - Incompressible and compressible (including transonic and supersonic) flows
 - Multiple frames of reference (flows in rotating machinery)
 - A large variety of boundary conditions, including periodic, non-reflecting, and moving
   boundaries  (e.g. for IC engines, pumps, turbines, propellers, mixers, stator/rotor
   interaction etc.)

Enhanced Treatment of Turbulence and Radiation Features
  - New turbulence models (DES, k-omega SST, V2f)
  - Hybrid wall functions removing near-wall Y+ constraints
  - New radiation models (discrete ordinates)

Chemical Reaction and Combustion
  - Multiple heterogeneous and homogeneous chemical reaction, including NOx formation
  - Built-in algorithms to calculate chemical equilibrium compositions
  - Combustion of gaseous, liquid and solid (e.g. coal) fuels
  - CHEMKIN and in-house complex chemistry solvers option with stiff chemistry capabilities
  - Special combustion capabilities for internal combustion engines (petrol and diesel)
  - Material properties database
  - STAR/KINetics for CFD coupled with chemistry
  - Weller 3-equation combustion model
  - New soot libraries for IC engines

Heat and Mass Transfer
  - Heat transfer by convection (with buoyancy) and conduction (in solids and baffles)
  - Thermal and solar radiation, including participating media
  - Mass transfer

Multiphase
  - Multiphase Lagrangean flows (dispersed gas/solid, gas/liquid, sprays, solid/liquid,
    liquid/liquid)
  - Two-phase flows, Eulerian approach
  - Free surface modeling and cavitation
  - Multiple fluid streams  - Distributed resistances (porous media)

Eulerian two-phase flow modeling
 - Catering for complete phase separation with sharp interfaces
 - Complex flow: gas bubbles, liquid drops and particle-rich flows
 - Heat transfer between phases
 - Free-surface flows with simultaneous heat transfer
 - Enhanced analysis of mixers and fluidized bed reactors

Multiphysics
 - Aeroacoustics
 - Fluid-structure interaction (various methods from loosely to fully coupled)
