1. Use of the flow of high-pressure combustion gas to generate electricity; especially, in high-voltage electric-power generation, air-pollution control, and paint spraying. 2. The conversion of heat energy into electricity by sweeping charged particles through an electric field in a stream of gas.

Electrogasdynamics is a procedure for generating electricity. Small particles of dust, smoke, fog, etc are charged in a low-voltage region and then transported by a gas stream to a high-voltage region, where the charges are removed.

Work is done on the particles in moving them against the electric field and electricity is generated.
