A tomographic measurement technique is applied for visualization of the local void fraction in the two phase flow of air and water in the mixing chamber of a two-phase-nizzle. With this measurement technique a high spatial and temporal resolution can be achieved. The measured physical property is the electric conductivity of the water. The conductivity is measured with pairs of wires strained in the investigated cross section. The measurement values are proportional to ralative liquid fraction. With an algebraic reconstruction technique (ART) the field of the liquid fraction in the investigated cross-section in calculated from the measurement values. The quality of the reconstruction is increased by a-priori-knowledge.
