From the results obtained in the study, the following conclusions can be made:The methylene blue and spectrophotometer method can capture the free radicals generated successfully. This is an effective way to measuring the free radicals quantitatively in cavitation, moreover it is easy to fulfill.The intensity of cavitation increases with reduction in the cavitation number. But the different mechanism of various enhancive processes (chemical and physical processes) results in different effect by cavitation number.The effect of operating parameters, such as inlet pressure, temperature and time on cavitation indicate that optimum operating conditions exist at the cavitation enhancive effect is maximum.It is important to optimize the structure of hydrodynamic cavitation reactor for achieving a desired effect. A reasonable geometric parameter can promote the enhancive effect for a fixed hydrodynamic condition.Ventilating appropriate gas to cavitating flow can increase cavitational intensity and hence promote the enhancive effect of hydrodynamic cavitation.

cavitation：空化

"空化"(cavitation)现象,也称"空穴"现象. 当物体在水中高速运动时,在固体和液体的交界面上,压力会大大降低,有时甚至会产生接近真空的负压,此时,即使是常温下,局部的水也会沸腾,形成低压的微小气泡(在0.02个大气压下,20℃的水就会沸腾).

cavitation：气穴现象

这种现象称为气穴现象(cavitation). 植物可通过某些方式消除气穴造成的影响,例如气泡在某些导管中形成后,它会被导管分子相连处的纹孔阻挡,气泡便被固定在一个管道中,当水分运动遇到气泡的阻隔时,可以横向进入相邻的导管分子而绕过气泡,

cavitation：气蚀

该元件主要是利用被称为气蚀(Cavitation)的流体中产生气泡的现象来去除污渍. 首先,使高速振动的元件加上水与衣物接触,在污渍附着的纤维缝隙中产生微小的真空气泡. 这些真空气泡便在衣物与振动器之间碰撞,通过这冲击可以将污渍弹出来.

cavitation：气穴

MEI YAN等离子熨体仪,正是运用无创技术迅速爆破击退脂肪,这台熨体仪透过高能量深层传送,利用 聚焦热能强声波头发射OOOHZ强烈震波acousticwave(声波的一种)震动脂肪细胞,继而在其中产生气穴(cavitation)作用现象,形成无数微细的真空气泡,
