Studies of the dynamic behaviour of charged dust particles in high electric fields using laser Doppler velocimetry

摘要: Abstract As a preliminary study for the collection of dust particles in an electrostatic precipitator, laser Doppler velocimetry has been used to measure velocity small charged high electric field model precipitator. A differential optical system is adopted velocimeter. The period-measuring analyse beat signals and obtain data from them. By means velocimeter, dynamic behaviour direction moving fully revealed as function applied voltage entire collecting space shown vectorial flow diagrams particle velocity.
