Entwicklung von Mehrphasenmesstechnik

Für die räumlich und zeitlich hochauflösende Prozess- und Strömungsdiagnostik entwickeln wir eigene Sensoren und Messverfahren. Der Fokus liegt dabei auf bildgebenden Messverfahren.

Needle Probes

Such probes allow the investigation of multiphase flows with liquid and gaseous phase components with a high temporal resolution.

Wire-mesh sensors

Wire-mesh sensors belong to flow imaging techniques and allow the investigation of multiphase flows with high spatial and temporal resolution. The wire-mesh sensor principle is based on a matrix-like arrangement of the measuring points.

Ultrafast electron beam X-ray computed tomography (ROFEX)

The high-performance ROFEX (ROssendorf Fast Electron beam X-ray tomography)imaging technique has been developed at Helmholtz-Zentrum Dresden-Rossendorf for the noninvasive investigation of dynamic processes.

Gamma-ray computed tomography

Gamma ray tomography is well suited to determination of phase fraction distributions in heavy and dense industrial devices and machines. For that the HZDR developed and operate a high resolution and transportable gamma-ray computed tomography scanner.

X-ray- and micro-focus X-ray-computed tomography

In the frame of research in thermal fluid dynamics we use X-ray radiography and tomography techniques for the measurement of gas and liquid hold-up in chemical vessels and experimental flow loops.

Optical Tomography

Optical tomography is currently being tested for imaging of gas-water flows at low gas fractions. With this technique it is possible to generate cross-sectional images of the temporal and time-integral gas distribution within a plane of a vessel or pipe.

Autonomous Sensor Concepts

The acquisition of spatially distributed ­parameters in large vessels is problematic, as sensor mounting or cable connections are not feasible or desired. The concept of instrumented flow followers helps to fetch spatially distributed process ­parameters in chemically and mechanically harsh environments of agitated industrial vessels.

Optical Micro-bubble Sensor

For the measurement of ­very small gas bubbles in fluids a special optical sensor was developed based on the principle of videoendoscopic flow observation combined with a sophisticated image processing software for detection and measurement of micro-bubbles.
