The difference in flow direction is believed to be a "skin effect" and not due to any deeper atmospheric processes.

The difference is that the flow direction after passing through the sleeve changes by 90 .

Two positions are catered for on the hanger, giving still more options of flow direction.

The pump swivel angle covers both positive and negative flow direction.

They then examined the preferred flow direction for the clusters within each slice.

In a valveless pumping system, no valves are present to regulate the flow direction.

Likewise, eddies may form in only one flow direction.

Normal: at 90 (perpendicular) to the shock medium's flow direction.

When designing an expansion joint with combination ends, flow direction must be specified as well.

These structures are easily definable because they lack symmetry parallel to the flow direction.
