However, this is not particularly practical as it would require large volumes of circulating gas.

A circulating gas sweeps particles from the chamber.

The circulating gas and the power fluctuations that accompanied it were eliminated by operating the fuel pump at slightly lower speed.

In the main cyclone burner, secondary air is introduced tangentially, causing a circulating gas flow pattern.

Each shelter has tiled floors, with large industrial sized gas stove islands and ceiling circulating gas furnaces.

Dr. Murphy said the FUSE data provided the "first good evidence" for the long-theorized "galactic fountain" cycle of circulating gas.

At a depth close to the radiation zone, these convective cells of hot gas are enormous, but at shallower depths the circulating gas organizes itself into progressively smaller "granulations," all of which are steps in the ladder carrying the Sun's energy from its depths to its surface.
