Abstract
This work is devoted to a numerical investigation on turbulent flow combining an oblique wall jet and an offset jet. This combination will be denoted the wall offset jet. Several turbulence models were tested in the present study, such as the standard k-omega, SST k-omega, standard k-epsilon, RNG k-epsilon, and the realizable k-epsilon models. A parametric study was also performed to pick out the wall inclination beta effect on the longitudinal and transverse positions of the merge points (MP), combined point (CP), upper vortex center (UVC), and lower vortex center (LVC). Analyzing the numerical results shows that increasing the wall inclination results in longitudinal displacement of the MP, CP, UVC, and LVC further downstream along the longitudinal direction reporting acceleration on the merging process launch. Furthermore, for higher wall inclination values, these characteristics points transversally deviate toward the oblique wall.
