Optical tomograph for the investigation of single and two phase pipe flows

We developed and tested an optical tomograph for the investigation of single and two phase flows in pipes or bubble columns. The device works similar to a conventional CT with 256 light emitters and 32 light receivers arranged about the object’s cross-section. The light emitters are sequentially flashed while the light receiver intensities are recorded synchronously. Primary area of application is single phase flows with dye tracers. Another potential application is the investigation of bubbly two phase flows at low gas fractions. Principle tests have been made for both problems.
