Comparison of the results of applying the turbulence model VT−92 and two-fluid model to the problem of a subsonic axisymmetric jet
This article studies an axisymmetric subsonic jet based on modern turbulence models. This task, despite its simplicity, is a rather complex problem for modeling turbulence. Therefore, many modern RANS models are not able to even qualitatively describe such problems. A comparative analysis of the tur...

description | This article studies an axisymmetric subsonic jet based on modern turbulence models. This task, despite its simplicity, is a rather complex problem for modeling turbulence. Therefore, many modern RANS models are not able to even qualitatively describe such problems. A comparative analysis of the turbulence models νt−92 and the two-fluid model for a submerged axisymmetric subsonic jet is carried out. For the numerical implementation of the problem, an implicit scheme was used. Comparative analysis was carried out for axial velocity, longitudinal velocity, transverse velocity and for turbulent stress. The obtained numerical results are compared with the results of NASA experimental data. It is shown that the two-fluid turbulence model more accurately describes turbulent flow than the turbulence model of the νt−92 model. |
