The phrase "a downstream section" is correct and usable in written English.
It can be used in contexts related to processes, systems, or geographical features where something flows or progresses from one point to another, typically in a linear or sequential manner.
Example: "The analysis focused on a downstream section of the river where pollution levels were significantly higher."
Alternatives: "a lower segment" or "a subsequent part".
The test chamber consisted of a rectangular-shaped upstream section (40-cm long, 24-cm wide, 14-cm water depth) and a trapezoid-shaped downstream section (40-cm long, narrowing to a 4-cm-wide back wall equipped with water run-off hoses).
A reduction of the heat and energy requirements in the downstream section will have a positive effect on the overall process efficiency, because more excess electricity will be available.
The test case of flow in the downstream section of a slot coater is used for three reasons: (1) it is an established benchmark; (2) it represents an idealized, yet industrially relevant flow; (3) high-fidelity results obtained with monolithic algorithms are available in literature.
Within this framework, a stock shortage affects the entire downstream section of the supply chain, regardless of the stocks kept in other locations.
A strict laminar flow in the downstream section of the chamber was unattainable because the relatively large butterflyfishes caused water turbulence during trials.
The findings also suggest that the characteristics of constrictions and the downstream section of pools provide an important control on scouring and sorting characteristics throughout the pool riffle morphology.
The geometry of a membraneless micro fuel cell influences reactant mixing and depletion in the downstream section of the cell channel.
In case of contingencies, after the fault area is isolated, MBESS will move to the downstream section, supplying buffering until the other DGs restarted in a controlled fashion to serve demand.
Under the current structure, parts of the downstream section fall within the third renewables arm, and there is a separate "gas" division.
