چکیده
|
Structure and principle of the new leakage current particulate matter (pm) sensor are introduced and further study is performed on the pm sensor with the combination of numerical simulation and bench test. high voltage electrode,conductive shell,and heaters are all built-in. based on the principle of venturi tube and maze structure design,this sensor can detect transient pm concentrations. internal flow field of the sensor and distribution condition of pm inside the sensor are analyzed through gas-solid two-phase flow numerical simulation. the experiment was also carried out on the whole sensor system (including mechanical and electronic circuit part) and the output signals were analyzed. the results of simulation and experiment reveal the possibility of pm concentration (mass) detection by the sensor. © 2016 jiawei wang et al.
