Comparison of numerical results of linear and nonlinear turbulence models based on the rans approach

E3S Web of Conferences, Journal Year: 2024, Volume and Issue: 587, P. 01003 - 01003

Published: Jan. 1, 2024

This paper considers one of the urgent problems modern physics — numerical solution turbulent flows, which play a key role in various fields science and technology, including aerodynamics, hydrodynamics heat transfer processes. The main attention is paid to comparison two turbulence models: linear model SST (Shear Stress Transport) nonlinear RSM (Reynolds Model). Both approaches are widely used for modeling but their efficiency accuracy may vary depending on nature flow. To compare these models, problem two-dimensional (2D) flow sharply expanding channel taken from NASA database was chosen. classic example complex flow, makes it ideal testing models. Sharp expansion leads effects, such as formation recirculation zones intense shear stresses, creates additional difficulties modeling. purpose this study assess how accurately each models describes processes flows identify strengths weaknesses. work included calculations based RANS approach (Reynolds-Averaged Navier-Stokes), by averaging Navier-Stokes equations over time. results both were compared with experimental data, allowed an objective assessment accuracy.
