Numerical Simulation of Free Surface in the Case of Plane Turbulent Wall Jets in Shallow Tailwater
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 کاملPlane Turbulent Jet Flow in a Favourable Pressure Gradient
SUMMARY An experimental study has been made of an incompressible turbulent plane jet exhausting downstream into an external flow having a favourable longitudinal pressure gradient approximating that of two-dimensional sink flow. Four flows were studied, for which the ratios of mainstream and jet velocities at the exit plane of the jet were in the range from 0.1 to 0.5. For each case velocity pr...
متن کاملLagrangian statistics across the turbulent-nonturbulent interface in a turbulent plane jet.
Lagrangian statistics from millions of particles are used to study the turbulent entrainment mechanism in a direct numerical simulation of a turbulent plane jet at Re(λ) ≈ 110. The particles (tracers) are initially seeded at the irrotational region of the jet near the turbulent shear layer and are followed as they are drawn into the turbulent region across the turbulent-nonturbulent interface (...
متن کاملLeaving on a plane jet
This is a continuation of our research on the Universal Planar Manipulator (UPM), a device capable of manipulating multiple generic objects (cans, chess pieces, poker chips, tools, etc.) with a single horizontally-vibrating, rigid plate (3 dofs). Objects are propelled by sliding frictional forces developed against the vibrating plate. A special plate vibration creates an average force field cal...
