Assessment of the applicability of different turbulence models in CFD simulations for the description of turbulent free jets during biomass combustion
A commercial CFD program Ansys Fluent 12.1 with different turbulent models was used to carry out the numerical study. Different turbulence models ( k –ε Standard, k –ε Realizable, k –ε RNG, k –ω Standard and k –ω SST) were used. Based on the present numerical solutions, new ...
An evaluation of ten turbulence models is made for compressible flows encountered in current aircraft applications. The Baldwin–Lomax and P.D. Thomas algebraic models, the Baldwin–Barth and Spalart–Allmaras one-equation models, five low-Reynolds-number k–ε models and the Menter SST blended k...

Evaluation of Various Turbulence Models in Predicting Airflow and Turbulence in Enclosed Environments by CFD: Part 2--Comparison with Experimental Data fro... Numerous turbulence models have been developed in the past two decades, and many of them can be used in predicting airflows and turbulence...
It was found that three turbulence models show a peak value in the ratio of mix to dead volume when the outlets were placed at 200 mm away from the wall. An APB was put on the bottom of the tundish surrounding the inlet jet when the outlets were kept at 200 mm away from the wall....
Zones with different turbulence model #1 Bert Guest Posts: n/a Hi, Is it possible to define 2 different zones in the same flow (same fluid) but with different turbulence models? Thanks. Thread ToolsSearch this Thread Show Printable Version ...
The flow fields around a bottom-mounted circular cylinder on rigid beds were simulated by solving the Reynolds-averaged Navier-Stokes equations with three different turbulence models. Numerical results were compared with several sets of experimental data. All of three turbulence models can reproduce flow...
Numerical simulation of three-dimensional circular free turbulent jet flow using different RANS turbulence models Modeling of turbulence heat transfer for supercritical fluids, using computational fluid dynamics (CFD) software, is always challenging due to the drastic ...

The performances of the different turbulence models were evaluated. For the tundishes that have been studied, the performances of the different turbulence models tested in the present work were similar. There is no evidence that any of the models provided sustained ...
