    en.wikipedia.org/wiki/Apache_Airflow

    Apache Airflow is an open-source workflow management platform for data engineering pipelines. It started at Airbnb in October 2014 [2] as a solution to manage the company's increasingly complex workflows. Creating Airflow allowed Airbnb to programmatically author and schedule their workflows and monitor them via the built-in Airflow user interface.

  4. Cleanroom - Wikipedia

    en.wikipedia.org/wiki/Cleanroom

    Laminar airflow systems are typically employed across 80% of a cleanroom ceiling to maintain constant air processing. Stainless steel or other non shedding materials are used to construct laminar airflow filters and hoods to prevent excess particles entering the air. Turbulent, or non-unidirectional, airflow uses both laminar airflow hoods and ...

  5. Surge in compressors - Wikipedia

    en.wikipedia.org/wiki/Surge_in_compressors

    The term describes violent air flow oscillating in the axial direction of a compressor, which indicates the axial component of fluid velocity varies periodically and may even become negative. In early literature, the phenomenon of compressor surge was identified by audible thumping and honking at frequencies as low as 1 Hertz, pressure ...

    en.wikipedia.org/wiki/Stack_effect

    The stack effect in chimneys: the gauges represent absolute air pressure and the airflow is indicated with light grey arrows. The gauge dials move clockwise with increasing pressure. The stack effect in industrial flue gas stacks is similar to that in buildings, except that it involves hot flue gases having large temperature differences with ...

  8. Pratt & Whitney PW1000G - Wikipedia

    en.wikipedia.org/wiki/Pratt_&_Whitney_PW1000G

    It aimed to cut fuel consumption by 6–7%, emissions by 15%, and generate less noise due to lower fan tip speed of 950 ft/s (290 m/s), down from 1,400 ft/s (430 m/s) in conventional 5:1 bypass turbofans. While the gearbox and larger fan weighed more, this was mitigated by using 40% composites by weight, up from 15%.
