Reynolds-averaged Navier-Stokes analysis

Reynolds-averaged Navier-Stokes analysis

[¦ren·əlz ¦av·rijd ¦näv·ē‚ā ′stōks ə‚nal·ə·səs]

(fluid mechanics)

The process of determining numerical solutions of the Navier-Stokes equations for a fluid flow, using time averaging of flow variables and modeling of turbulent stresses to simplify the calculations. Abbreviated RANS analysis.
