Gaseous particles or gas-entrained particles may be conveyed by electric fields acting on charged species included in the gaseous or gas-entrained particles.

Method for electrodynamically driving a charged gas or charged particles entrained in a gas

A charge electrode configured to impart a time-varying charge to a flame and a shape electrode located outside the flame may be driven synchronously by a voltage source through time varying voltage(s). The flame may be flattened or compressed responsive to an electric field produced by the shape electrode acting on the charges imparted to the flame.

System and method for flattening a flame

Apparatus for electrodynamically driving a charged gas or charged particles entrained in a gas

A heat exchange system includes an electrode configured to electrostatically control a flow of a heated gas stream in the vicinity of a heat transfer surface and/or a heat-sensitive surface.

Method and apparatus for electrical control of heat transfer

A combustion system may include a plurality of heated volume portions. At least two of the plurality of heated volume portions may include corresponding respective electrodes. The electrodes may be driven to produce respective electric fields in their respective volumes. The electric fields may be configured to drive desired respective responses.

Electric field control of two or more responses in a combustion system

According to an embodiment, combustion in a combustion volume is affected by at least two sequentially applied non-parallel electric fields. According to an embodiment, a combustion volume is equipped with at least three individually modulatable electrodes. According to an embodiment, an electric field application apparatus for a combustion volume includes a safety apparatus to reduce or eliminate danger.
