Modeling of turbulent opposed-jet mixing flows with \(\tilde\kappa\)-\(\tilde\epsilon\) model and second-order closure (Q1434627)

This paper presents a study (with extensive comparisons with experimental data) of turbulent opposed-jet flows using one-dimensional formulation with both \(\widetilde\kappa\)-\(\widetilde\varepsilon\) and Reynolds stress models. Both experimental data and numerical results using Reynolds stress models show that the turbulence is highly anisotropic. The numerical model confirms that the velocity and scalar fields are not affected by the bulk velocity in accord with experimental observation.
