Wall-jet flow is an important flow field in hydraulic engineering, and its applications include flow from the bottom outlet of dams and sluice gates. In this paper, the plane turbulent wall jet in shallow tailwater is simulated by solving the Reynolds Averaged Navier-Stokes equations using the standard turbulence closure model. This study aims to explore the ability of a time splitting method ...
متن کاملLarge eddy simulation of compressible turbulent jets
Increasing noise regulation at urban airports force jet engine manufactures to develop and build quieter engines. Over the last 10-15 years, a significant reduction in fan and mechanical noise has been achieved. However, the reduction in jet noise over the same time period is fairly small and a major reduction in acoustic emissions of jet engines has to come from a reduction in jet noise. Tradi...
متن کاملNumerical Simulation of Nonpenetrative Turbulent Thermal Convection
Nonpenetrative convection Ð in which the lower boundary condition is one of constant heat flux and the upper boundary is insulatedÐ is an idealization of penetrative convection, which finds application in the planetary boundary layer. Three-dimensional, unsteady, ( ) direct numerical simulations 96 = 96 = 128 have been performed of turbulent, nonpene7 trative thermal convection inside a cubical...
متن کاملEntrainment Characteristics of Turbulent Round Gas Jets Submerged in Water
The entrainment process in two-phase buoyant jets differs significantly from their singlephase counterparts, and is not well understood. Entrainment models developed for singlephase flow are often used in two-phase jetting simulations, albeit with limited success. In this work, Particle Image Velocimetry (PIV) and shadowgraph flow visualization experiments have been conducted on submerged round...
