摘要
水击驻波场处理油包水型乳化液是一门新兴工艺,稳定驻波场的存在是破乳的关键,而水击压力波波速在驻波场形成中起着重要的作用。因此,为了更精确的求解水击波速,从W/O型乳化液两相流产生水击现象的特点出发,根据流体力学的连续性原理,推导其水击波波速的表达式,并与经典单相流水击波波速公式进行对比,通过MATLAB仿真分析与对比验证,表明此水击波速公式既适用于单相流水击波速的计算,也适用于两相流水击波速的求解,且W/O型乳化液中含水量越大,其波速就越大。
The application of standing wave field occurred by water-hammer in water-in-oil emulsion is a new technology.And the existence of stable standing wave field is the key to demulsification.The velocity of water-hammer pressure wave plays an important role in the formation of standing wave field.Therefore,in order to solve the water-hammer wave speed more accurately,embarked from the characteristicses of water-hammer produced in W/O emulsion which is the two-phase flow,according to the principle of continuous fluid,the expression of water-hammer wave speed is inferred and is compared with that of classical water-hammer wave speed in single-phase flow.The simulations with MATLAB software and the verifications by contrast indicate that this formula is not only suitable for the water-hammer of single-phase flow,but also the two-phase flow.And the more water it contents in the W/O emulsion,the higher wave speed.
