The measurement technique of LaserDopplerVelocimetry (LDV) is one of the most frequently applied modern measurement techniques in fluid mechanics to perform accurate local flow velocity measurements, which exhibits the advantage of a very high local and temporal resolution. Our technical department offers excellent conditions to perform such measurements (LDV).

In various chemical or physical and technical processes particles of the order of 1 μm up to a few mm in size appear, whose size distribution is decisive or important for the process. There are many technical examples like in food production, pharmacy, process engineering, fuel burning in turbines, motors etc., slurry burning, and cosmetics. The laser diffraction particle sizer is capable to measure a particle size distribution from a collective of particles like a spray and to appropriately process, describe, and present it. The particle material may be solid or liquid in a gas or gas like air bubbles in a liquid. For the measurement it is only important, that the optical properties of the continuous and the dispersed phase are different. The laser diffraction particle sizer offers the advantage of a fast and non invasive measurement in a wide range of particle sizes. Especially in case of sprays or suspensions this method has become a standard measurement tool.

Particle size measurements are important in various applied sciences and in engineering, for example in fuel burning or in cavitation research as well as in particle size control. In all these applications it necessary to have knowledge about the particle dynamics. To gain that knowledge one has to measure the particle size and its velocity if possible in a noninvasive way with high local and temporal resolutions. A device which makes such measurements possible is the so called PhaseDopplerAnemometer (PDA), which has several advantages. First, it exhibits a large dynamic range from micrometer particles up to sizes in the millimetre range. Then it is very precise and no calibration procedure is necessary. Moreover, it is very robust against optical distortions. In the following the working principle of this flow and particle measurement technique will be explained.
