为提高CdS光催化降解性能,通过水热法合成了具有Cd空位缺陷的Cd_(1-x)S,并将其应用于光催化降解罗丹明B(RhB).结果表明,可见光照射下反应40min后,Cd_(1-x)S对RhB的光降解率达到98.1%,降解速率常数k=0.08649min^(-1),光催化活性远高于CdS.自由基淬灭实验结果表明,·O_(2)-为Cd_(1-x)S光催化降解RhB的主要活性物种.UV-vis、XPS、EPR表征结果表明,Cd空位的引入拓宽了Cd_(1-x)S的带隙宽度,抑制了可见光的吸收,证明了Cd_(1-x)S活性的提升并非源于能带结构的改变.密度泛函理论计算结合PL表征表明,Cd空位的引入导致了CdS局域电子密度不对称,促进空穴传输和载流子分离,从而显著提高了Cd_(1-x)S的光催化活性.

高速航行体肩部附着空泡穿越自由液面过程中发生溃灭现象,将产生巨大的冲击载荷,严重影响航行体出水姿态和结构安全性。该研究采用改进型分离涡模型,建立了水下发射非定常空化特性数值模拟方法。结果表明:航行体附着空泡出水过程自上而下发生溃灭现象,在溃灭末期收缩为较小的孤立空泡,溃灭产生的高速射流冲击结构表面;在出水过程中,水面附近的“反向旋转涡对”导致附着空泡发生了快速溃灭现象,以发卡涡为代表的壁面涡旋结构发展明显受到附着空泡的抑制;空泡溃灭末期的孤立泡产生了巨大的冲击压力峰值,对航行体结构安全性将造成巨大破坏。初期航行体迎流侧空泡溃灭行为也会导致较大的压力峰值出现。
