Outline of Final Research Achievements

An exhaust gas particle purification device using a plasma discharge from a magnetic functional fluid is proposed and developed for collecting micro- and nano-size exhaust gas particles without re-entrainment and pressure loss. A magnetic fluid is selected as the magnetic functional fluid, and the collection principle of the nonthermal plasma (NTP)-magnetic fluid filter is established.
Through experiments, the plasma discharge conditions are varied, and the collection efficiencies of the NTP-magnetic fluid filter are clarified. By conducting these academic studies, it is concluded that the pressure loss is extremely low, and the collection efficiencies are high.
