The present work is devoted to the Rayleigh–Taylor instability of dilatant and Newtonian fluids. The main aim of this work was to carry out experiment, numerical simulation of mixing of two media, and making a comparison between gained data. A series of experiments was carried out to study the Rayleigh–Taylor instability of a dilatant liquid, which is a mixture of potato starch and water. The initial perturbation of the liquid-air interface is given by the shape of the metal profile separating the two media. The difference in the development of this instability in water-air and dilatant fluid-air systems is shown.

牛顿膨胀流体系统的瑞利-泰勒不稳定性的实验和数值研究

目前的工作致力于膨胀和牛顿流体的瑞利-泰勒不稳定性。这项工作的主要目的是进行实验，两种介质混合的数值模拟，并对获得的数据进行比较。进行了一系列实验来研究膨胀液的瑞利-泰勒不稳定性，膨胀液是马铃薯淀粉和水的混合物。液体-空气界面的初始扰动是由分隔两种介质的金属型材的形状给出的。显示了水-空气和膨胀流体-空气系统中这种不稳定性的发展差异。
