입자의 형상에 따른 열영동 영향에 대한 실험적 연구

Abstract

Agglomerated and non-agglomerated S1O2 particles are synthesized m a fiimace by oxidation of TEOS vapor These polydispersed particles are classified with DMA to extract particles. Then these particles are introduced into a thermal precipitator through the ESP(Electrostatic Precipitator) to investigate the themophoretic particle deposition using CNCs(Condensation Nuclei Counter) The efficiency of themophoretic particle deposition according to agglomerated and non-agglomerated particles m the thermal precipitator has been studied as a ftinction ofpartide size and TEOS mole concentration using monodisperse particles classified by DMA The results show that the particle deposition efficiency decreases as TEOS mob concentration increases and particle size increases Therefore, U is concluded that the ihermophoxetic deposition efficiency is dependent of the particle morphology
