Reynolds-Averaged Navier-Stokes (RANS)

The Reynolds-Averaged Navier-Stokes (RANS) equations are a set of mathematical formulas used to model fluid flows, like air or water, when turbulence is involved. Instead of calculating every tiny swirl and eddy directly, RANS averages these chaotic movements over time, resulting in smoother flow predictions. This approach simplifies complex calculations, making it possible to efficiently analyze and predict the behavior of turbulent fluids in engineering applications, such as aircraft design or weather forecasting, while still capturing the essential effects of turbulence on the overall flow.
