The more common non-convecting solar pond reduces heat loss by preventing convection (the transfer of heat from one place to another by the movement of fluids) with the addition of a concentration of 20 30 percent salt to the bottom level (lower convective zone) of the pond.
The squadron will be collaborating with the Fourth Convection and Moisture Experiment (CAMEX-4), organised by NASA, America's National Aeronautics and Space Administration, in a rare integration of that agency's responsibilities for flight within and beyond the atmosphere.
Rather than rain, though, it is the idea of fiddling with clouds' brightness that interests Alan Gadian of the University of Leeds, in Britain, and his team.In this section Now you don't Journalistic deficit disorder Clouds over troubled waters Magic mushrooms ReprintsA hurricane forms when intense sunlight heats the surface of the sea, driving both evaporation and convection.
Because less heat is generated, small water-cooled reactors can use simpler designs relying not on pumps, but on natural convection.
HEAT, as every schoolboy (and schoolgirl) knows, moves in three ways: conduction, convection and radiation.
That suggests a lot of rapid convection in the Earth's interior (though not as rapid as in Dr Fauve's simulation, since things are happening on a grander scale, and in liquid iron, not liquid sodium).This result certainly clears up one mystery.
He insisted that the original Macintosh computer, launched in 1984, should not have an internal cooling fan, but rely instead on convection cooling to keep it quiet.
The winds whose energy derives from the sun, via the convection of air currents are increasingly harnessed by windmills both on- and offshore.
How about a tiny fan that consumes a fraction of the energy of a traditional fan and removes heat twice as fast as natural convection.
Termites also build sheltered tunnels from their mounds to the outside world, to keep themselves safe while they are foraging.In this section Sheathing Cupid's arrow 'Bot the builder Secondary goals ReprintsIndividual termites are, of course, far too dim to understand such things as convection and solar flux.
Convection is the mass movement of a fluid: hot water rising, for example.
