Numerical Predictions of Three Parallel Jets Interaction

摘要: This work is about the interaction of three parallel non-ventilated turbulent slot jets. The central jet set symmetrically between two identical lateral heated There are so many applications this flow configuration in engineering such as gas turbine airfoils, heating or cooling surfaces, combustion and mixing flow. Computations achieved by finite volume method. numerical predictions confirm types patterns given available visualization. Furthermore, a fourth type pattern found paper. For distance neighboring jets 11 times nozzle thickness (D0 = 11a), effects velocity ratio on dynamical thermal fields examined. Therefore, contours streamlines, vorticity, pressure, kenetic turbulence energy isotherms for several ratios (0.3 ≤ λ 15), discussed Several temperature gaps (10°C ΔT≤ 50°C) considered. Both cent...
