An empirical method is presented toselect the proper type of a mean diameterfrom experimental data, if this meandiameter is not known a priori fromtheoretical reasoning. The method isillustrated by four examples rangingfrom granulation of detergent to a visualranking of bubble size distributions ofchocolate mousse samples. For each sam-ple size distributions as well as productproperties are determined to test therelevance of the selected mean diameters.

This work deals with the application ofdifferent in-line methods based on tur-bidity signal analysis to the characteriza-tion of silica aggregate size and morphol-ogy. Furthermore, the determination ofmorphological characteristics of the ag-gregates along with the number of theirconstituting particles is discussed. Simi-larities between the different methodsare examined and discussed.

The dispersion behavior of agglomeratesof several grades of fumed silica in siliconoils has been studied as a function ofparticle morphology and applied flowconditions. The effects of primary particlesize, aggregate density and structure oncohesivity were probed through tensileand shear strength tests on particle com-pacts.

The problem of computing light scatter-ing by cylindrical fibers with high aspectratios in the framework of the Null-FieldMethod with Discrete Sources is treated.Numerical experiments for investigatingthe scattering properties of two fibergeometries are performed.

Experiments and numerical simulationsof the behavior of the particulate phase ina highly turbulent gas flow in a verticalchannel with different obstacles are pre-sented. Especially particle – obstaclecollisions and crossflow in the vicinity ofa jet nozzle are investigated. The simu-lation results show good agreement withthe experimental results.

This paper presents the application of amonitoring technique using electrical re-sistance tomography for controlling theoptimum polymer dosage for sludge dew-atering. It is demonstrated how polymerdosage leads to a change of floc sizedistribution and that they can be moni-tored using the tomography technique.

The diffusional collection efficiency ofaerosols in the low Knudsen numberregion is studied including the effect ofgas slip at the collector surface. Compar-ison with experimental results showsgood agreement. Therefore, the obtainedequation can be used for a broad range ofcollector sizes, pressures and tempera-tures.
