摘要

The accurate study of heat transfer between water and steam at high pressures was achieved on a developed and tested model of a mixing unit for heat transfer flows (Direct-Contact Water Heater — DCWH). The test results showed that the water underheating to the saturation temperature at the model outlet is less than 1 and 2°C for two- and single-tray arrangement of the water-separation unit in the model, respectively. The droplet flow model is preferable for thermal calculation of the heating block in the DCWH.
