Messverfahren zur Bestimmung des Staubungsvermögens von dispersen Pulvern

Dustiness Measuring Methods of Disperse Powders Industrial handling of bulk materials, for example to store, convey, mix, fill etc. often leads to dust emissions. Generated dust is closely related to health hazards and environmental pollution and often leads to fires and explosions. The dust liberation property of powders depends on a multitude of variables and also on the method and intensity of stressing. The present paper describes further developed resp. used dustiness measuring methods. It also describes particle measurement techniques and summarizes the measurement methods systematically.     

Verbesserung des Fluidphasenresonanzmischens mit OpenFOAM

This work shall improve fluid phase resonance mixing for two applications: smooth, and intense mixing. Knowledge from previous work and CFD simulations with OpenFOAM are being used for this purpose. The two newly created variants are simulated as instationary flows of two separate phases with 2D and 3D CFD models. The results of the 3D simulation are additionally verified by laser doppler anemometry.
