Experimental and Numerical Study of Confined Coaxial Turbulent Jets

The turbulent mixing of a primary jet and its surrounding fluid in a pipe with inlet conditions that result in flow separation is studied. Detailed profiles of the axial mean and rms velocities have been measured with a laser Doppler anemometer. Measured spectra of axial velocity fluctuations show the presence of coherent structures. The performance of a two-equation turbulence model in conjunc...

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 ...

Acoustic Simulation of Hot Coaxial Jets Using Cold Helium-air Mixture Jets

This work examines the ability of small-scale, helium-air-mixture, coaxial jets to capture the acoustics of large-scale hot jets representing the exhaust of separate-flow turbofan engines. Experiments at University of California, Irvine (UCI) employed a one-eighth-scale model of a separate-flow nozzle being used at the Nozzle Acoustic Test Rig (NATR) of NASA Glenn Research Center. Comparisons w...

Acoustic Simulation of Coaxial Hot Air Jets Using Cold Helium–Air Mixture Jets

This work examines the ability of small-scale helium–air mixture coaxial jets to simulate the acoustics of largescale hot air jets representing the exhaust of separate-flow turbofan engines. Experiments employed a one-eighthscale model of a separate-flow nozzle used in hot tests at NASA John H. Glenn Research Center. Comparisons were conducted for two set points using the following methods: mat...

A Numerical Investigation of Impinging Jets

Steady, incompressible flow solutions are found numerically for a radially expanding liquid sheet in order to confirm analytical results for inviscid flow and to investigate viscous and nonlinear effects. An hp-finite element method is used to perform the numerical simulations. Comparisons are made to theoretical predictions of the radius where the sheet becomes unstable. To determine the criti...
