The observation can be explained by buoyancy due to changes of electrolyte density during the electrochemical reaction which leads to convection. "It was surprising to see that tiny changes in ...

What is right, he explained, is that fluids' boundary layers, not the strength of the Coriolis and buoyancy forces, control the rotating convection system. A boundary layer is a sliver-thin layer ...

Figure 1: Flow driven by buoyancy and osmotic sources in saturated ... pumping can be at least 10 times larger than in seeps with convection induced by salinity and thermal differences.

Heat, mass, and momentum analogies. Turbulence. Buoyancy-driven flows. Convection with phase change. Radiation exchange between surfaces and radiation transfer in absorbing-emitting media. Multimode ...

These classroom demonstrations were designed by Prof. John Hart at the University of Colorado Boulder. Construction of the experiments and filming of the clips on this website was carried out by Scott ...

What could be more simple than that? Not much, actually. The physics behind a hot air balloon is buoyancy. When heated, the air inside the balloon becomes less dense than the surrounding atmosphere.

In space, there is no buoyancy. So investigators heat one disc higher than the other to induce Marangoni convection in that bridge of silicone oil. They are looking at patterns of how fluids move ...

Because gravity is necessary for density differences to arise, neither buoyancy nor convection occur in a zero-gravity environment such as space. Consequently, the combustion products accumulate ...

Convection, or the flow of mantle material transporting heat, drives plate tectonics. As envisioned in the current research, heating at the base of the mantle reduces the density of the material, ...

Even with all the hype about forced convection cooling, many applications in the electronics cooling industry still depend on natural convection cooling. Christopher A. Soule, Thermshield, LLC ...

In this installment of Hot Science we present three questions that may help you to better understand buoyancy. The first is a kind of warm-up question, dealing with general buoyancy principles.
