| 摘 要： | 应用超空泡原理,提出一种新型的海水淡化装置--旋转超空泡蒸发器.为研究从空泡中抽取蒸汽对旋转超空泡蒸发器水动力学特性的影响并确定抽汽量,对一定转速和不同抽汽量下的旋转超空泡蒸发器超空化流动进行数值模拟.结果表明:抽汽量随抽汽压力的降低而线性增大.相比未抽汽工况,抽汽对超空泡的面积和体积有较大影响.抽汽后抽汽量的变化对超空泡面积和体积的影响较小.

| Abstract: | With the application of supercavitation effect, a novel device named rotational supercavitating evaporator (RSCE) has been designed for seawater desalination. In order to study the effect of steam extraction on hydrodynamic characteristics of RSCE and then determine the steam extraction rate, numerical simulations are carried out on the supercavitating flows in RSCE at a constant rotational speed and at different steam extraction rates. The results show that steam extraction rate linearly increases with the decrease of extraction pressure and that the area and volume of the supercavity could be significantly affected by steam extration, as compared with the case without steam extration.However, both of them vary slightly with the increase of steam extraction rate in the process of steam extraction. |
