| 英文摘要 | Swirl flow through a concentric annulus is a fundamental flow encountering in the cases of swirl flow type heat exchanger, cyclone and other equipment. However the estimation method of pressure drop in the swirl flow through annulus has been scarcely investigated. In this paper, an empirical equation for friction factor defined as Fanning equation is obtained as a function of Reynolds number, ratio of inner tube diameter to outer one an aspect ratio of inlet section. This empirical equation for overall friction factor in the swirl flow through annulus is applicable within errors of ±20% under given experimental conditions. |
