Available in PDF, EPUB and Kindle. Book excerpt: The origin and the structure of undulance and turbulence in stably stratified media are investigated through theoretical reasoning and laboratory experiments. The mechanisms for generating turbulence in stably stratified media are linked with the mechanisms for generating vorticity - shear and stratification. The dual role of stable stratification -- the capability for generating and attenuating turbulence -- is pointed out. The turbulence induced by stable stratification is evidenced in two experimental results: (1) turbulent rotors in the lee of a barrier in a stably stratified fluid, and (2) the breaking of traveling internal waves on a sloping surface. The ability of stable stratification to generate turbulence is also indicated from an exact solution for an inviscid stably stratified flow past a barrier. The structure of undulance and turbulence in stably stratified media is investigated in a stratified salt water towing tank, with schlieren photographs, quartz-coated hot-film probes, and single electrode conductivity probes. The schlieren photographs show clearly the collapse of a turbulent wake and the attenuation of turbulence by stable stratification. Auto-correlations and -spectra for the streamwise turbulent velocity field and for the turbulent concentration field are obtained. From the measured correlations and spectra, the combined wave-turbulence behavior is clearly shown, and the turbulence is strongly anisotropic. (Author).

Download or read book Buoyancy Effects in Fluids written by John Stewart Turner and published by Cambridge University Press. This book was released on 1979-12-20 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomena treated in this book all depend on the action of gravity on small density differences in a non-rotating fluid. The author gives a connected account of the various motions which can be driven or influenced by buoyancy forces in a stratified fluid, including internal waves, turbulent shear flows and buoyant convection. This excellent introduction to a rapidly developing field, first published in 1973, can be used as the basis of graduate courses in university departments of meteorology, oceanography and various branches of engineering. This edition is reprinted with corrections, and extra references have been added to allow readers to bring themselves up to date on specific topics. Professor Turner is a physicist with a special interest in laboratory modelling of small-scale geophysical processes. An important feature is the superb illustration of the text with many fine photographs of laboratory experiments and natural phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: Propagation of internal gravity waves over a slope in a fluid with constant Brunt-Vaisala frequency was studied in a wave tank. Wave motion in the fluid interior was measured with conductivity probes, and in the boundary layer, with dye streaks and neutrally buoyant particles. Outside the breaking zone, the amplitude and horizontal wave number of high-frequency waves increase linearly with decreasing depth; this is in agreement with existing linear, inviscid solutions. Well upslope, a zone of breaking or runup is produced by the high-frequency waves. If the wave characteristics are closely parallel to the bottom slope, upslope propagation of low-frequency waves produces a line of regularly spaced vortices along the slope, which slowly penetrate into the fluid interior; mixing in these vortices sets up thin horizontal laminae that are more nearly homogeneous than adjacent layers. A criterion for incipient motion of bottom sediment under shoaling internal waves was developed using available theoretical solutions for velocity in the viscous boundary layer, found to be valid for certain experimental conditions.
