Abstract
In this present study, the round jet impingement on flat plate is analyzed numerically using four different RANS turbulence models. The four turbulence models considered are k-ω SST, realizable k-ε, RNG k-ε and ν2f. The numerical results in terms of turbulent kinetic energy have been compared with the previously published experimental results for the purpose of validation. It has been observed that ν2f model predicted the variation in turbulent kinetic energy accurately in the wall jet region above the near wall as compared with other models.
