Experiments in ground-test facilities are required to develop and mature aero-optic platforms. However, structural vibrations of the facility can introduce significant error in optical experiments, making it difficult to separate wind-tunnel dynamics

We seriously challenge the belief that tidal-channel data of Grant et al. support the theory for the classical energy-spectrum behavior, ϕ ∝ k −5/3 in the inertial subrange (where k is wave number and ϕ(k) is the one-dimensional energy-spectrum

We derive properties of turbulence in a homogeneous, incompressible, Newtonian fluid. The discussion features au invariant N (characteristic circulation in material circuits containing vorticity but imbedded in nearly irrotational masses of fluid). T

This paper describes a general procedure for real-time calibrated measurement of skin friction using hotfilm sensors controlled by a constant voltage anemometer (CVA). Hotfilms are sensitive to air and substrate temperature and compensating for tempe

The following paper is the first of a series of two relating to the problem of internal oscillations of a fluid in a gravity field with vertical gradients of density and velocity. The theoretical analysis in this paper will be supplemented by a repor

An experimental study was carried out to investigate the effect of rotation on turbulent mixing in a stratified fluid when the turbulence in the mixed layer is generated by an oscillating grid. Two types of experiments were carried out: one of them i

This paper discusses critically observations of mixing processes across density interfaces in laboratory experiments and inferences that have been made and can be made from these observations. Fluxes of heat or salt and entrainment velocities have be

The paper discusses an idealized experiment relevant to the flow of air over a heated surface. Two regimes are found and expressions are obtained for buoyancy and momentum fluxes q and τ, mean buoyancy and mean velocity gradients ρz and uz, rms vel

This paper describes a laboratory experiment designed to compare measurements with published theoretical ideas of the mixed-layer growth of a two-layer system in which the turbulence is induced by an oscillating grid. Experimental results show excell

A laboratory experiment was performed to investigate mixing across a density interface which separates two turbulent fluid layers and coexists with a stabilizing buoyancy flux. It was found that the buoyancy flux ( q 0 ) across the interface and thro
