ALAQS- CFD Comparison of Buoyant Free and Wall Turbulent Jets

This report investigates the effects of a solid boundary on the flow properties of a buoyant jet. A comparison was made with the results of a previous ALAQS report on an unbounded jet to highlight the difference jet behaviours. It is believed that the inclusion of the wall represents a further step towards a better understanding of the source dynamics behind an airplane jet engine during the ta...

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 ...

Scaling, spectra and zonal jets in beta-plane turbulence

A beta-plane approximation of the two-dimensional quasigeostrophic model describes a single layer ~barotropic! fluid subjected to a latitudinally varying Coriolis parameter or topography. Rhines ~1975! initiated the study of beta-plane turbulence. He predicted the inverse energy cascade into predominantly zonal modes, hence an array of eastward–westward jets, and estimated the jet number ~celeb...
