Modeling (selection of models)

CFD codes typically designed for solving certain fluid

 phenomenon by applying different models

Viscous vs. inviscid  (Re)

Turbulent vs. laminar (Re, Turbulent models)

 Incompressible vs. compressible (Ma, equation of state)

Single- vs. multi-phase (Ca, cavitation model, two-fluid

  model)

Thermal/density effects and energy equation

   (Pr, , Gr, Ec, conservation of energy)

Free-surface flow (Fr, level-set & surface tracking model) and

  surface tension (We, bubble dynamic model)

Chemical reactions and combustion (Chemical reaction

  model)

etc…
