The hydrodynamic cavitation phenomenon included inception, development and the collapse of the hydrodynamic cavitation has been reviewed.Three models have been proposed to explain the cavity collapse. The high pressure and temperature which the collapsed cavities generated can be used as a method of energy imput. The paper also includes that the hydrodynamic equipment and the applications. This is important for the further research.

Using the energy released in hydrodynamic cavitation to enhance some chemical reaction is a new approach to energy utilization.It is very important to establish quantitatively the relationship between the amount of hydroxyl radical induced in hydrodynamic cavitation and the strength of hydrodynamic cavitation.In this paper methylene blue was used as the catcher for hydroxyl radical induced in hydrodynamic cavitation and an ultraviolet-visible spectrophotometer was used to measure the amount of induced hydroxyl radical.The influences of upstream pipe pressure,liquid temperature and time interval on the amount of induced hydroxyl radical were also experimentally investigated.Meanwhile the suitable temperature and pressure were also established under experimental conditions.The results constituted the fundamentals to quantitatively study the strength of hydrodynamic cavitation and to effectively enhance some chemical reaction.

利用空化释放出的能量对过程进行强化是能量利用的新途径。定量分析空化引发.OH产量与空化强度的关系,对研究空化对过程的强化效应有着十分重要的意义。以亚甲基蓝作为羟自由基捕捉剂,利用紫外-可见分光光度法,间接测定了水力空化产生的.OH产量。分析了管路上游压力、液体温度、空化作用时间等宏观参数对自由基产量的影响,以及自由基产量与空化强度的关系,寻求出有利于空化发生以及提高空化作用强度的适宜操作条件。
