recirculation rate

He screwed it into a ball, removed the service panel from the machine and, after a moment's study, adjusted the recirculation rate of the developing vapour.

In spark ignition engines, both alcohols can run at a much higher exhaust gas recirculation rates and with higher compression ratios.

High liquid recirculation rates are used to reduce tube wall temperatures, thereby reducing polymerization on the tube and associated fouling.

The methods used to mitigate exposure will include providing high air recirculation rates in the airlock, the use of a "Double Shell Spacesuit", the use of dust shields, the use of high grade magnetic separation and the use of solar flux to sinter and melt the regolith.
