What is RANS?

RANS (Reynolds-Averaged Navier-Stokes) is a mathematical model used in computational fluid dynamics (CFD) to simulate fluid flow. It simplifies the Navier-Stokes equations by averaging them over time, which reduces the computational cost. RANS models are commonly used in engineering applications to predict flow behavior around objects, in pipes, and in other systems where detailed turbulence simulation is not required or computationally feasible.

RANS Competitor Technologies

LES

Large Eddy Simulation (LES) is an alternative turbulence modeling approach to RANS. It resolves larger turbulent eddies while modeling smaller ones, offering higher accuracy than RANS but at a greater computational cost. Therefore, it is a competitor to RANS.
