Measurement Techniques for Multiphase Flows
Measurement Techniques for Multiphase Flows
Prasser, H.-M.
Abstract
The lecture presented an overview of the state of art of instrumentation for transient and staedy state multi-phase flows with a special attention to gas-liquid flows. The methods discussed are: impedance probes, wire-mesh sensors, optical fibre probes, gamma tomography, X-ray tomography, 3D pulsed holography, neutron radiography. Short descriptions of the measuring methods developed in Rossendorf were included. This concerns electrical impedance probes, wire-mesh sensors, gamma-tomography for periodically changing transient gas fraction fiels (e.g. in axial pumps and turbo couplings) and highthe status of the development of a -speed X-ray tomography system on the basis of a scanned electron beam.
Keywords: multi-phase flow; impedance probes; wire-mesh sensors; optical fibre probes; gamma tomography; X-ray tomography; 3D pulsed holography; neutron radiography
