Electrical Tomography applied to two phase (gas/liquid, gas/solid) flows

Electrical tomography can give great insights into multiphase flows. But more than that they can give quantitative information on concentrations and velocities. This talk will describe two tomography instruments: Wire Mesh Sensors and Electrical Capacitance Tomography. I will discuss their testing and application. The former to gas/water and gas/oil flows the latter to gas/oil and gas solids flows. A number of features of the flow that have been found will be illustrated.
