<hr />
<div>Turbulence modeling is a key issue in most CFD simulations. Virtually all engineering applications are turbulent and hence require a turbulence model.<br />
<br />
==Classes of turbulence models==<br />
<br />
*RANS-based models<br />
**Linear eddy-viscosity models<br />
***Algebraic models<br />
***One and two equation models<br />
**Non-linear eddy viscosity models and algebraic stress models<br />
**Reynolds stress transport models<br />
<br />
*Large eddy simulations<br />
<br />
*Detached eddy simulations and other hybrid models<br />
<br />
*Direct numerical simulations<br />
<br />
