A research focus of the Institute of Particle Process Engineering of the University of Kaiserslautern-Landau is the development of methods for particle concentration, size (mean- and distribution) and velocity measurement with DES- (Dynamic Extinction Spectroscopy). A extinction measurement setup which combines dynamic (statistical) and spectral evaluation methods. The 3D LSS (Light Scattering Sensor) developed at our institute represents another unique sensor setup to measure the sphericity of single particles by interpreting intensity profiles of defined scattering and azimuth angles. A main research aspect is the inline implementation of the measurement method in industrial relevant applications. To successfully accomplish new sensors for specific particle systems, the experimental and simulative experience of more than 10 years is gathered. It was conducted under the direction of Prof. Ripperger and will continue under his successor, Prof. Antonyuk.
Our research verified the SE-Method as suitable for particle system from 1 µm to about 3 mm and up to 30 vol% concentration to deliver reliable and reproduceable measurements in sprays, emulsions and suspensions.
The future research will be focused on the application of the DES setup for particle sizes starting at 1 nm.
