【 摘 要 】

The laboratory setup was developed for studying the water vapor condensation process from the gas mixture on a vertical flat heat exchange surface in rectangular channel 10x2 cm. The experiments were carried out with normal pressure of steam-air mixture. The results allowed to determine the heat transfer coefficient from steam-gas mixture to the heat transfer surface. The dependences of the heat transfer coefficient on the initial moisture content and the mixture flow rate in the heat exchanger channel were obtained.
