An Introduction to Gravity Currents and Intrusions by Marius Ungarish

By Marius Ungarish

Gravity currents and intrusions are the ever-present phenomena the place a fluid of 1 density flows horizontally right into a fluid of a unique density. For researchers and engineers, the power to appreciate and expect those movement fields is key in wide-ranging purposes together with these concerned with atmospheric and ocean dynamics, the propagation of pollution, and the dispersion of volcanic clouds. even if many new theories, experimental facts, simulation effects, and insights have surfaced lately, almost all these advancements stay scattered in journals and convention papers.  A systematic and unified advent to the sector, which includes the recent effects and advancements, is sure to facilitate the applying of the on hand wisdom to either sensible difficulties and extra investigations.    Written via a famous authority energetic in contemporary advancements in gravity present study, An creation to Gravity Currents and Intrusions presents an up to date, self-contained, and systematic creation to the research, interpretation, and prediction of gravity present flows. the writer makes use of an easy mathematical framework to supply an obtainable and accomplished advent to the mathematical and actual elements of this crucial subject. The textual content provides researchers and practitioners with the basis required to formulate difficulties, interpret experimental effects and measurements facts, receive easy and insightful analytical estimates and suggestions, and increase or enforce numerical codes for similar difficulties. The booklet additionally issues out gaps of data within the present figuring out that require additional examine.  This obtainable reference calls for just a simple history in fluid mechanics and utilized arithmetic, making it an incredible origin for researchers and engineers new to the sector. it may additionally function a textbook for upper-level undergraduate and graduate point classes in fluid dynamics.

Example text

The current is thin and we therefore consider F r to be a constant. 68) where K and β are some positive constants. The similarity coordinate is y = x/(Ktβ ) in the range [0, 1]. The obvious boundary condition is U(1) = 1. The form of h is inspired by continuity consideration; we expect ϕ = CV/xN (t), where V is the volume of the current, in general a time dependent variable, but a constant in the present case. The objective is to determine ϕ(t), β, U (y), H(y), and K. 67). 69) and H(1) = F r−2 .

8)) to achieve a sharp numerical interface. We consider currents with H = 3. 5, and the grid is 200 × 200. This configuration is compatible with typical laboratory saltwater experiments in an open tank of about 15 cm × 200 cm (height × length) and at least 10 cm width. 5 are displayed in Fig. 9. 5, for H = 3 and HS F r function. 1) after release. The current is deep: H = 7 (dimensionless). The dotted vertical line indicates the position of the lock gate, and the thin lines are at 10 cm intervals.

52). The solution is now straightforward. 55), for the two unknowns u and h. We must carefully determine the origin of the two characteristics (denoted by + and −) which arrive at this point; this specifies the values of the appropriate Γ± . We thus obtain u and h. , contradictory, or insufficient, information at some points), the trajectories of the characteristics are easily determined, and the trajectory of the nose (the line ON ) is straight. Consider the W OL characteristic region. , Γ+ = −Γ− = Υ(1) = 2.
