WebSep 27, 2024 · Mass flows of water, or currents, are essential to understanding how heat energy moves between Earth’s water bodies, landmasses, and atmosphere. The ocean covers 71 percent of the planet and holds 97 percent of its water, making the ocean a key factor in the storage and transfer of heat energy across the globe.

WebSep 10, 2009 · Gravity currents intruding into a uniformly stratified ambient are examined in a series of finite-volume full-depth lock-release laboratory experiments and in numerical simulations. Previous studies have focused on gravity currents which are denser than fluid at the bottom of the ambient or on symmetric cases in which the intrusion is the ...

WebMay 1, 2024 · Fig. 9. Carbon dioxide mass fraction contours of backdraft at 0.25, 0.5, 0.75 and 1.0 g. The above results indicate that even at reduced gravity, the phenomenon of backdraft can still occur. The question is whether backdrafts at reduced gravity have comparable strengths to those corresponding to normal gravity.
WebJun 1, 1994 · The time-dependent shallow-water solution for a gravity current propagating in a channel of finite depth reveals that the flow must remain subcritical behind the leading edge of the current (in a framework relative to the head). This constraint requires that hf/d ≤ 0.347, where hf is the height of the front and d is the channel depth. nature laboratory investigation 影响因子WebMar 1, 2014 · Fig.3.
