Abstract

Abstract

Through condensation tests of air-containing steam outside the tube against the 3×3 tube bundle with different tube diameters and inclination angles, the basic laws of heat transfer tube diameter and inclination angle affecting the condensation heat transfer of air-containing steam outside the tube bundle are studied. The results show that the effects of tube diameter and inclination angle are significantly different in different pressure ranges. At pressures below 0.8 MPa, the condensation heat transfer coefficient increases with the decrease of tube diameter and inclination angle, and the condensation heat transfer coefficient of 12 mm and 0° inclination angle heat transfer tube is 29% higher than that of 19 mm and 90° inclination angle. At pressures above 0.8 MPa, the condensation heat transfer coefficient decreases with the decrease of the tube diameter, up to 18%; with the decrease of the inclination angle, the condensation heat transfer coefficient first decreases and then increases, and the condensation heat transfer coefficient is the smallest at an inclination angle of about 60°.
