CLOGGING OF AN ELECTRICALLY ACTIVE FIBROUS FILTER MATERIAL - EXPERIMENTAL RESULTS AND 2-DIMENSIONAL SIMULATIONS

An experimental study has been undertaken in which the loading behavio ur of an electrically active fibrous filter material has been investig ated. In these experiments both filter pressure drop and penetration h ave been monitored continuously while samples of filter material have been loaded with monodisperse stearic acid particles. This paper conce rns itself only with the pressure drop data. The experimental findings suggest that electrically active materials should have greater dust h olding capacities than conventional materials, and a mechanistic expla nation as to why this should be is presented. This mechanistic explana tion is supported by two-dimensional simulations of dendrite formation .
