Abstract The major goal of this study is comparing the results of heterogeneous and homogeneous condensation through a CD nozzle. The experimental technique for liquid phase assessment in wet steam transonic flow is tested under real conditions in an in-house steam tunnel test rig. The flow was modelled numerically using an in-house CFD code for performing the heterogeneous and homogeneous condensation models. For the comparison between CFD results and experimental data, the static pressure distribution throughout the nozzle bottom wall were chosen. One may observe a good agreement of the CFD results with experimental data. The presented approach can be used in the future for searching the reasons for the lack of accuracy between experimental and numerical static pressure distribution in the condensing steam flows.
