Fundamental characteristics of low-resistive particulate matter removal using a magnetic fluid and nonthermal plasma

Abstract Diesel engines have advantages such as high energy density of fuel, high efficiency, and relatively low CO2 emission. Therefore, diesel engines are preferred for various applications, such as automobile and ship. Despite the advantages, emission of particulate matters (PMs) from the diesel engines is a grave environmental concern. To address the issue, here, a magnetic fluid filter aided with nonthermal plasma (NTP) for removing diesel particulates without causing any loss in the pressure is proposed. The working principle of the proposed filter and the methodology for evaluating the PM removal efficiency are discussed in the paper. Further, the experimental results including the performance of the proposed filter are analyzed. The feasibility and high efficiency of the filter are evident from the results.
