Micro-scale simulation of fibrous liquid aerosol filters

D. Hoch*, A. Baumann, J. Niessner, Heilbronn University of Applied Sciences, Germany

Today aerosols are produced in many industrial processes like machining, manufacturing of catalysts or in pneumatic compressors. While the harmfulness of fine dust aerosols is well known the equally dangerous liquid aerosols (mist) receive less attention. In order to be prepared for future legal regulations we develop efficient mist filters with less energy consumption.

We present first results of micro-scale simulations of mist deposition on fibrous structures. In our framework, the fibrous structure is obtained from ┬ÁCT scans. Micro-scale simulations provide information on fractional efficiency as well as parameters and constitutive relationships for macro-scale simulation used to investigate pressure drop. Therefore, the micro-scale simulation is closely linked to the macro-scale simulation.

The aim is to develop fibrous mist filters with less energy consumption (reduced pressure drop) and increased fractional efficiency compared to existing filters...
