Summary
The
Reynolds Averaged Navier-Stokes
(RANS) equations are a set of time-averaged equations for
Fluid Flow
, designed to predict the
Mean flow characteristics
in
Turbulent Flows
. They simplify the complex,
Chaotic nature of turbulence
by
Averaging out the fluctuations
, making it feasible to solve practical
Engineering problems
with reasonable
Computational Resources
.
