Comparison of measurement and simulation of particle deposition at charged microfibers

چکیده
In the field of aerosol filtration, electrostatic effects are relatively unexplored but absolutely decisive in many applications (Rengasamy, 2009). It is possible to adjust and improve the particle deposition for synthetic filter materials to increase the initial filtration efficiency. E.g. it is used in respiratory protective devices, cabin air filters or air conditioning systems. The measurement and simulation techniques for electrostatic forces respectively charges still need to be investigated. To determine the influence of the charged fibres for the filtration efficiency three different methods can be obtained, measurements, empirical formula and 3D modeling. The general setup for the experiments is shown in figure 1.

Introduction: The goal of any type of radiation therapy in the treatment of tumors, in addition to destroying cancer cells, is to minimizing radiation to nearby healthy cells and thus reducing side damages. For this purpose, targeted radiation therapy (TRT) is more effective in treating of single cells or small cluster of cells. The main factor in the success of this method is...

The capture efficiency of the small aerosol particle is strongly influenced by the structure of fibrous layers. This study presents particle deposition and dendrite formation on different arrangements of binary fibers. 2-D numerical simulation is performed using the open source software of OpenFOAM. In the instantaneous filtration of a single fiber, obtained results are in good agreement with th...
