摘要：

Heat transfer from a wedge in air-water mist flow has been measured over a mass flow ratio M from 0 to 3 × 10-2. Addition of small quantities of water-droplets to air stream enhanced two-phase heat-transfer coefficients h(2) from 2 to 14 times the corresponding single-phase ones. While the value of h2 increases with increasing the wall temperature Tw at high mass flow ratios, it decreases with increasing Tw at low mass flow ratios, particularly in a dryout state. Generally h(2) increases with M and approach velocity. These tendencies are well explained by the present first-order theory. © 1979.
