| 摘 要： | 利用计算流体力学软件Phoenics对海水淡化装置中的闪发腔内的流场进行计算,并分析绕流板的设置对湍流度的影响。由于以往对提高海水淡化装置特别是多级闪发装置(MultiStageFlashMSF)效率的研究多局限于提高热效率的方面,或者是采用化学的方法,而忽视了从流体力学角度通过改变闪发腔内流动情况来提高效率。因此,本文通过对海水淡化装置闪发腔内流动情况的数值模拟,探索提高效率的方法。

| Abstract: | Numerical Modeling is presented to study the flow field of flashing chamber in seawater-desalting devices using software PHOENICS. The effect of the setting of blocking boards on the flow structure is also discussed. By the optimization of the flow structure in flashing chamber, a method is proposed to improve the efficiency of seawater-desalting setting, and is different from the traditional methods which focus on thermal efficiency or chemical methods. |
