    Abstract: An electrostatic precipitator may have different collecting and repelling electrodes surfaces. For example, a collecting electrode may have an internal conductive portion. A non-conductive or less conductive open cell foam covering may be applied to the conductive core of the collecting electrode. The foam may have cell sizes that vary within the volume of the foam or along the length of the foam. Accordingly the cell size of the foam near the leading, with respect to the direction of airflow, portion of the collector may be larger than the cell size of the foam nearer the trailing end of the collector and/or the cell size of the foam near the exterior of the collector may be larger than the cell size of the foam nearer to the interior of the collector.

    Abstract: Dielectric barrier discharge plasma actuators are described. In one embodiment, a fluid flow actuator includes: a dielectric sheet; and a first electrode of a dielectric barrier discharge-direct current augmented (DBD-DCA) actuator disposed on a first face of the dielectric sheet. The first electrode is exposed to a surrounding fluid. The fluid actuator also includes a second electrode of the DBD-DCA actuator disposed on a second face of the dielectric sheet. The second face of the dielectric sheet is opposite from the first face of the dielectric sheet. The first electrode and the second electrode are configured for receiving an alternating current (AC) voltage configured to locally ionize the fluid and to generate ions. A third electrode located downstream from the first electrode and the second electrode. The third electrode is configured for receiving a direct current (DC) voltage configured to accelerate the ions.

    Abstract: An electrostatic precipitator may have a set of collector electrodes and a set of repelling electrodes. The conductive portions of the collector electrodes and/or the repelling may be arranged in segments. The segments may have differing electrical properties or may be electrically isolated to facilitate differing potentials along an airflow path. The differing potentials results in differing electric field strengths along the airflow path.

    Abstract: An electrostatic precipitator is constructed with collecting and repelling electrodes. The collecting electrode is partially shielded from gas shear forces by a shielding structure. The shielding structure is mounted to reduce gas flow along a surface of the collector and includes passages for charged particles to travel to be captured by the collector.
