AU - Chen, Hai-Bo. N1 - PDF for print: pp. PY Plumes are fluid motions that are produced by continuous sources of buoyancy. Convective currents set up by heated bodies such as a cigarette and a space heater are examples.

The fluid in contact with the body attains a higher temperature than its surrounding fluid, rises as a result of its lower density, and in so doing draws ambient fluid The plumes might be this small, but they could be as big as 1–2 km in diameter, in which case they could be somewhat slower.

As discussed, plumes erupting more slowly could also reach 8 km if condensation continues after eruption, but in either case the plume will stop at about 8 km because of the increasing atmospheric temperature (buoyancy Mechanics of turbulent buoyant jets and plumes / by E.J.

Responsibility: The river spread laterally from the mouth and formed a thin surface buoyant plume with various shapes that have not been previously reported.

To understand the influence of different driving forces, primarily wind, buoyancy, and ambient currents, extensive field experiments were carried out over four periods in August and Juneand June (ASCE)HY Turbulent Jets and Plumes introduces the fundamental concepts and develops a Lagrangian approach to model these shear flows.

This theme persists throughout the text, starting from simple cases and building towards the practically important case of a turbulent buoyant jet in a density-stratified  › Environmental Sciences › Environmental Engineering and Physics.

We present the results of a double-plume integral model for a positively buoyant multiphase plume of liquid carbon dioxide injected at mid-depths ( – m) in the ocean. In addition to the relevant plume physics, the model accounts for dissolution of the carbon dioxide droplets, the effect on dissolution of clathrate hydrate films, and the increase in seawater density due to enrichment (ASCE)()().

The mechanics of submerged turbulent jets has received a good deal of research attention. This work has resulted in an understanding of the process by which jets grow by entrainment of surrounding fluid. While of direct scientific interest, this work has practical implications that are of interest to engineers concerned with the design of systems that utilize jet ://   The concept of mantle plumes, hot buoyant rock masses that rise in the mantle, is a key to understand intraplate volcanism in the framework of modern plate tectonics.

Recent progress in instrumental, analytical and satellite technology enables scientists to verify the plume hypothesis with seismic tomography, isotope geochemistry and other sophisticated :// 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.

Plume conditions were simulated using dense gas sources (carbon dioxide and sulfur hexafluoride) in a still air ://   Experiments on the onset of buoyant instabilities leading to periodic formation of vortical structures in planar buoyant plumes of helium and helium/air mixtures injected into quiescent air are reported for a range of nozzle widths (w=20–70 mm), plume fluid densities (pure helium to that approaching air), and velocities at the nozzle exit.

First, the plume parameters corresponding to the In other fields of geophysics, buoyant plumes and jets are known to play important roles in oceanic mixing processes, both at the relatively large scale (as in deep water formation by convective sinking) and at the relatively small scale (as with plume formation beneath ice leads, for example) › Physics › Classical Continuum Physics.

Turbulent Entrainment in Buoyant Jets and Plumes. The behavior of turbulent buoyant jets in uniform density environments is found to be governed by an entrainment function and buoyancy function, both of which are functions of the local jet densimetric Froude number and the local jet spreading angle.

For plumes, Batchelor's analysis is used to show that the local Froude number and jet angle are ?dockey= @article{osti_, title = {HGSYSTEM/UF{sub 6} model enhancements for plume rise and dispersion around buildings, lift-off of buoyant plumes, and robustness of numerical solver}, author = {Hanna, S R and Chang, J C}, abstractNote = {The HGSYSTEM/UF{sub 6} model was developed for use in preparing Safety Analysis Reports (SARs) by estimating the consequences of possible accidental releases of.
