The phrase "air loop" is correct and usable in written English.
It can be used in contexts related to aviation, HVAC systems, or any situation involving air circulation or flow.
Example: "The engineers designed an efficient air loop to improve ventilation in the building."
Alternatives: "air circulation system" or "airflow circuit".
Air loop reactors (ALR) have been widely used as promising and high-efficiency gas liquid and gas liquid solid reactors.
The new designed DRHRS is directly connected to the primary loop, which consists of three independent parallel loops, three intermediate cooling circuits and an air loop.
The influence of operating conditions and geometric configuration on the distribution of bed density is discussed in a cold model annulus-lifted air loop reactor.
The ventilated cavity is undesirable since it reduces the driving force for liquid circulation when the pipe is the downcomer of an external air loop fermenter or analogous gas/liquid reactors.
One-dimensional drift flux mixture flow model is used for analysis of the steam water loop, whereas single-phase fluid model is applied to single flow in primary system and air loop.
I seemed to be flying through the air, looping the loop, making me dizzier than ever.
When it actually took off, in a 1917 test flight, it shot bravely into the air, looped the loop and crashed yards from the lorry that launched it via a pneumatic catapult.
It consists of a pair of hot and cold air loops that serve as thermal reservoirs, and a mixing box to mix the hot and cold air streams supplied from the loops.
In view of these differences, distinct hydrodynamic behaviour can be anticipated for the gas solid annulus-lifted air-loop reactor.
The present paper proposed a novel gas solid air-loop reactor treating fine Geldart A particles and operating in a new annulus-lifted mode, with bubbling or turbulent bed upward flow in the annulus in parallel with bubbling bed downward flow in the draft tube.
A one-to-one scale test section of the HEMJ divertor reference geometry has undergone testing in an air flow loop under a wide range of operating conditions that include the Reynolds number of the actual helium-cooled HEMJ design.
