摘要: Abstract In this study, the performance of a thermal precipitator disk-to-disk type was investigated experimentally and numerically. The prototype basically two disks separated via circular Teflon® spacer. temperatures (one at elevated temperature other room temperature) were individually controlled by silicone heating element running water temperature. Monodisperse particles sodium chloride fluorescein used to investigate particle collection efficiency when operated under various aerosol flowrates gradients. Our experimental data showed that remained approximately constant for test with diameters smaller than 300 nm noticeably decreased as diameter increased beyond 300 nm. A numerical model developed calculated in reasonable agreement experiment observations. Finally, simple estimate typical precipitator. indicated is function cold-disk deposition area, average thermophoretic velocity, flowrate. This may be useful future design similar configurations.
