An Acoustic Transmission Tomography for Measuring Gas Holdup in Multiphase Flows

Multiphase flows with gas holdup are found in numerous process engineering applications. A targeted flow and process optimization of the plant technology requires a profound un derstanding of the process. A vital characteristic of these processes is the spatially resolved gas holdup, which describes the local ratio of the bubble volume to the total volume under consideration.
