FLAME CONTROL IN THE MOMENTUM-DOMINATED FLUID DYNAMICS REGION

摘要

A combustion system includes a fuel nozzle and first and second electrodes. An electric charge is applied to a flame supported by the nozzle via the first electrode. An electrical potential applied to an aerodynamic surface of the second electrode. The electrically charged flame reacts to the electrical potential according to the respective magnitudes and polarities of the charge applied to the flame and the electrical potential applied to the aerodynamic surface. Where the polarities are the same, the flame is repelled by the aerodynamic surface, and where the polarities are in opposition, the flame is pulled into contact with the aerodynamic surface by the electrodynamic attraction.
