AN EXPERIMENTAL STUDY OF MASS AND HEAT TRANSFER FROM ROTATING BLADES
Аннотация
The investigation of mass and heat transfer from straight radial blades rotating in the air have been carried out by means of a naphthalene sublimation method. The measurements were carried out within the range of rotational Reynolds numbers from 1.19 × 104 to 31.1 × 104. The results of the measurements on a rotating blade and on its windward and leeward sides were generalized by means of functional dependences of Sherwood and Nusselt numbers on a rotational Reynolds number. The average values of mass and heat transfer from a rotating blade and from its windward side are compared with those published in literature concerning similar cases of flow. This comparison also shows the convenience of using the Chilton - Colburn heat - mass transfer analogy factor in the case investigated.
