理论研究首先包括湍流液体中液滴破碎的柯尔莫戈洛夫-欣策理论的适用性，并在每单位液体质量从 5 到 109W kg−1 的局部功率耗散范围内对其进行测试。其次，湍流脉动速度与搅拌容器中叶轮叶片的尺寸和转速有关。第三，分散相粘度对液滴尺寸的影响包含在一个新的、简单的基础理论中，该理论使用搅拌罐、静态混合器和均化器的数据进行了测试。
Theoretical studies include firstly, the applicability of the Kolmogoroff-Hinze theory of droplet break-up in a turbulent liquid, testing it over a range of local power dissipations per unit mass of liquid from 5 to 109W kg−1. Secondly, the turbulent fluctuation velocity is related to the size and rotational speed of the impeller blades in agitated vessels. Thirdly, the influence on droplet size of the viscosity of the dispersed phase is included in a new, simple basic theory, which is tested using data on agitated tanks, static mixers and homogenizers.
