Abstract

The article is devoted to the new approach to acceleration of technological processes in viscous and fine-dispersed media due to the influence of high-intensity ultrasonic vibrations, which provides formation of cavitation. It is shown that the existing method for calculation of required power of the ultrasonic technological devices cannot be used for designing special equipment intended for processing of high-viscosity and fine-dispersed liquid media. The improved method for calculation of necessary intensity of ultrasonic influence is proposed. In this method cavitation mode takes place in viscous and fine-dispersed media in order to reveal required power operating conditions of the ultrasonic electronic generators. The obtained results allows recommending the choice of optimum intensity (up to 30 W/cm2) of the ultrasonic influence in liquids with the viscosity of up to 0.6 Pa·s (oil, glycerin, epoxy resin and others), which are widely used in the practice.

粘性和细分散液体介质中最佳空化影响强度的计算方法

本文讨论了在高强度超声振动的影响下，在粘性和细分散介质中加速工艺过程的新方法。结果表明，现有的超声工艺装置所需功率的计算方法不能用于设计用于处理高粘度、细分散液体介质的专用设备。提出了一种计算必要超声影响强度的改进方法。在这种方法中，在粘性和细分散的介质中发生空化模式，以揭示超声电子发生器所需的功率工作条件。所获得的结果可以推荐在粘度高达0.6 Pa·s的液体(油、甘油、环氧树脂等)中超声波影响的最佳强度(高达30 W/cm2)的选择，这在实践中被广泛使用。
