摘要: The heat and mass transfer from a grooved tube is investigated experimentally for falling-film flow. experiments are conducted on helical trapezoidal at three temperatures of the feeding water: 30°C, 35°C, 40°C. Reynolds number (Re) air ranges between 1,500 3,500. Nusselt (Nu) expressed as function Prandtl (Pr), Re (Rea), water (Rew); Sherwood (Sh) Schmidt (Sc), Rea, Rew, correlation coefficients determined.
