Steps

  1. 01
    chemical → thermal · loss to radiative
    • fuel, oxidiser and an ignition source; flame temperature 1500–2500 K
    gas · above ~700 K
    refs [1]
  2. 02
    Combustion —produces→ Hot gasestablishedclaim record
    thermal → thermal
    refs [1]
  3. 03
    thermal → kinetic · loss to thermal
    • the gas has an upstream pressure state above the downstream nozzle or duct pressure
    gas
    refs [2] [3]
  4. 04
    kinetic → kinetic
    • a directed high-speed gas stream leaves the nozzle — the disequilibrium whose content is bulk fluid motion
    refs [3] [2]
  5. 05
    kinetic → electrical · loss to thermal
    • a dielectric fluid carrying injected charge is driven by the flow against an electric field to a collector electrode
    bulk flow required · electric field or bias required
    refs [4] [5]
  6. 06
    electrical → electrical
    • monopolar charge injected into a dielectric liquid (n-hexane in the 1977 generator) is carried by the flow against the field to a collector
    refs [4] [5]
  7. 07
    electrical → electrical · loss to thermal
    • charge collected at an electrode and driven through an external load at the potential the flow maintains
    refs [4] [5]
