Description
  • The approach used in the paper for the condensation of flowing steam is based on the binary nucleation of water and a representative chemical impurity NaCl. The physical and mathematical models are briefly described. The binary nucleation numerical model is tested on steam flow with condensation in a Laval nozzle with a low expansion rate of about Pr = 1000 s-1 in the divergent part of the nozzle. The calculated results for the pressure distribution are compared with experiments. The binary nucleation numerical model is used for the calculation of steam flow with condensation in the 2D nozzle-blade cascade of the first wet stage of the low-pressure (LP) part of a condensing steam turbine. Calculations of the flow in the cascade at high and low expansion rates are presented.
