عنوان انگلیسی CFD Investigation on the Steady Interaction between an Offset Jet and an Oblique Wall Jet
چکیده انگلیسی مقاله In this paper a CFD investigation on the interaction between an offset jet and an oblique wall jet using two-dimensional 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).
