Diesel Exhaust Particles (DEPs) are the problem of air pollution in high concentration the closing space such as long-distance tunnels of highway. Electrostatic precipitators (ESPs) are installed in a tunnel to collect particulates that principally involve DEP. They are suitable for decontaminating polluted gases and improving the visibility index in road tunnels, thereby saving drivers and improving the air environment around the tunnels. In this study, the underlying data of ESP performance was extracted in condition of high gas flow velocity. The gas flow velocity was in the range of 10 to 25 m/s. The experimental ESP was two'stage'type which composed of a prechager, followed by the collection section. The high voltage electrode in the charging section was sawtooth type. The collection efficiency for experiment and the simulation were compared. The constitution of the ESP units to collection efficiency was considered.
