“…The present computational results have also been compared for a single wall jet (Re=10000) with the experimental results of Wang and Tan [56] (Re=10000) and the LES results of Dejoan and Leschziner [10] (Re=9600). The results of these validations have been given in Mondal et al [36]. It is found that the present computational results are at least as accurate as the published LES results; in A C C E P T E D M A N U S C R I P T some cases the present k − computations agree more closely with the experimental results than the LES computations.…”

In this paper a CFD investigation on the interaction between an offset jet and an oblique wall jet using twodimensional steady RANS equations is performed. This combination is denoted WOJ (Wall Offset jets). Several turbulence models such as the standard k-ω, SST k-ω, standard k-ε, RNG k-ε and realizable k-ε models are tested in the present study. A parametric study is performed to highlight the wall inclination effect on the WOJ flow maximum velocity decay as well as the shear layers spreading. Comparison between combined wall and offset jet (WOJ) and single offset jet (SOJ) flows is also established. Results show that increasing the wall inclination improves the combined wall and offset jets flow spreading. Furthermore, the outer shear layers spreading, is better than the inner shear layers one. Comparing to the combined wall and offset jet flow (WOJ), a better spreading is found in the case of single offset jet flow (SOJ).

“…Mondal et al [7][8][9] numerically investigated the interaction between wall jet and offset jet at different velocity ratio (0.78-1.34) for Reynolds number 10000. The height of the wall jet was varied in the range of 0.2 to 2.…”

In this study, the two-dimensional, incompressible numerical analysis is carried out to understand the turbulent fluid flow physics and thermal characteristics of a dual jet consisting of a wall jet and a parallel offset jet using standard k-RNG turbulence model. The study is carried out to compare the flow and thermal features of the dual jet for an offset ratio of 3, 7 and 9 at different Reynolds numbers in the range of 5,000 to 20,000. The results of the flow field and turbulent behavior of a dual jet are illustrated in the form of temperature contours, velocity vectors, streamlines, and turbulent kinetic energy at different Reynolds number and offset ratio. The effect of offset ratio and Reynolds number on recirculation region and intensity of upper and lower vortices are discussed in detail. The velocity variation along the axial and vertical direction are also discussed.
