Assessment of plate-wire electrostatic precipitators based on dimensional and similarity analyses

► Dimensional analysis may be used as an inspection method to the performance of an ESP. ► By physical similarity a functional dependence of penetration is achieved. ► Particle collection yield is checked through the flow, electric and material conditions. ► Two non-linear regression models were verified in a pilot electrostatic precipitator. ► This analysis is a useful and reliable scaling-up tool between physically similar ESPs.
