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。
Water hammer standing wavefield processing water-in-oil emulsion is a new technology. The existence of stable standing wave field is the key to demulsification. The wave 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 velocity more accurately, the expression of water hammer wave velocity from the W / O emulsion two-phase flow is deduced based on the continuity principle of fluid mechanics. The comparison of wave velocity equations of single-phase flow shock wave shows that this wave velocity wave velocity formula is suitable for both the calculation of single-phase flow velocity and the wave velocity of two-phase flow, and the W / O The larger the water content in emulsions, the greater the wave velocity.
