He still describes the downflow as being the "percolating."

And, with no further conversation, he stepped into the shaft, glided around the downflow, and van- ished upward.

The preferred and most modern type of WESP is a downflow tubular design.

The initial downflow of air from an approaching storm produces a huge yellow wall of sand and clay that can temporarily reduce visibility to zero.

In front of these piers, decelerating flow and friction with the bed material causes a downward pressure gradient that leads to erosive downflow.

It floated, and spun in the downflow of water, and water splashed into the hollow of it, and stayed there.

Unlike inline and angle pattern the discharge of a downflow pattern is outward and is not contained by the valve itself.

Up through there, up through that pounding, drenching downflow, with water in my nose and eyes and ears, and no idea what was on the other side?

The cooling units can be mounted on the roof (down draft, or downflow), or exterior walls or windows (side draft, or horizontal flow) of buildings.

Upturned beds are mounds of elongated sediment that are deposited on the lee (downflow) side of an obstruction, containing form-concordant stratification.

True to his word, the scientist proved his assess- ment of an existing downflow by leaving the second floor in a direction that carried him to the center of the shaft.

The Evershed effect is common to every spectral line formed at a temperature below 10 K; this fact would imply a constant downflow from the transition region towards the chromosphere.

That heat is then rejected to the atmosphere by the partial evaporation of the water in cooling towers where upflowing air is contacted with the circulating downflow of water.

If an undergravel filter is in use, whether downflow or reverse-flow, then extra biological filtration is totally unnecessary within the canister which could be put to better use with chemical media.

The filter bed arrangement for reverse-flow is exactly the same as the downflow method, but the direction of water is reversed and pumped down the uplifts and up through the various media.

The first US patent for a "Coffee Percolator," but still using a downflow method without rising steam and water, was issued to James Mason of Franklin, Massachusetts, in 1865.

Downflow fume hoods, also called downflow work stations, are typically ductless fume hoods designed to protect the user and the environment from hazardous vapors generated on the work surface.

Pastel plasterwork crumbled away from the wall of cheap yellow brick that crowded up against it, shedding its mortar in loose flakes, or absorbed the sordid staining from a cracked downflow pipe, pooling in fetid puddles at its base.

Forward chines also act as Leading edge root extensions (LERX) at low speeds and high angles of attack, generating a downflow over the inboard wing to reduce its angle of attack and delay the stall, and also generating vortices which provide additional lift.

It is possible that Marstonia comalensis became extinct at Comal Springs when this water body temporarily dried in 1964; it is also possible that the shells of this species which have been found at this site were washed downflow from extant populations in the headwaters of the Guadalupe River.
