旋转圆筒上多孔介质对流传质的喷射强化研究

AUGMENTATION OF CONVECTIVE MASS TRANSFER ON POROUS MEDIUM SURFACE OF ROTATING CYLINDER UNDER IMPINGING JET FLOW

本文采用喷射气流强化旋转圆筒上薄多孔介质表面的对流传质,分析了旋转速度,喷射述度,喷嘴宽度,喷射距离等因素的影响,推荐了对流传质关联式;对因旋转的影响而产生的第一和第二临界点进行了论述和验证。

The influences of the rotating speed, velocity of jet flow, width and the distance of nozzles from the surface on mass transfer are expressed by a relationship and compared with the heat transfer. The phenomena of the first and second critical points are especially demonstrated.
