Gas-gas single phase mixing were numerically evaluated with static mixer and without static mixer using OpenFOAM and ANSYS Fluent codes. The main goal was the gas-gas mixing simulation comparison between ANSYS Fluent and OpenFOAM. The same ANSYS mesh was used for each case in both codes. The “reactingFoam” solver and species transport models were used for handling the species in OpenFOAM and ANSYS Fluent respectively. The reactingFoam solver is a transient solver and ANSYS Fluent was simulated at steady state condition. Standard k-e model was used to predict the turbulence effect in both computational fluid dynamics codes. OpenFOAM gave a higher mixing level compared to ANSYS Fluent. Chemical species momentum predictions are more diffusion in OpenFOAM and more convective in ANSYS Fluent.

Keywords: OpenFOAM, ANSYS Fluent, CFD, mass fraction, standard deviation, mixing
