Particle characterization technology
Innovative laser techniques for particle size determination
Non-contact optical in-situ measurements of particle concentration, particle size distribution and particle velocity in two- and multiphase flows are offered.
Particles
– Diameter range: 1µm to mm
– Particle concentration: 1 per cm³ to 5000 per mm³ (depending on the dispersed phase and the marginal parameters of the problem)
– Particle velocities: 0 m/s to 300 m/s
Measurable process parameters
– Particle size distribution (e.g. diameter distribution, Sauter-Mean diameter,…)
– Concentrations (e.g. volume concentration, void fraction, particle number concentration,…)
– Rivers (volume flow, mass flow,…)
– Particle velocities
– Differentiation of disperse phases / particle classification
Used optical measurement techniques
– Phase Doppler measurement technique
– Hydrodynamic Nuclei Concentration Technique (HDNC technique)
– Shadow imaging techniques
Applications
– Spray characterization (nozzles, atomizers, coating processes)
– Bubble measurements (bubble inclusions, cavitation nucleis)
– Environmental monitoring (bubble entry, suspended matter concentration)
