The article describes experimental and computational methods used for calculating some current aerodynamic characteristics of the air-cooled condenser circle channel. It also determines the temperature fields at the diffusor outlet as well as the condenser surface of an area-averaged heat-transfer coefficient as a function of the air speed at the inlet of the heat-exchange units. The authors registered spatial velocity fields at both the inlet and outlet of the air-cooled condenser circle channels as well as an active pulsation of the air speed. The authors establish the technical basis for estimating metering and pressure characteristics of both the air-cooled condensers and a heat-transfer coefficient.
