Relaxation Phenomena in Liquids and Glasses and Pattern Formation in Fluids

9410478纳格尔技术摘要：我们将用不同的光谱技术来研究过冷液体中的弛豫现象，包括比热、介电光谱、剪切模数和四极磁化率。介电光谱学将以超过14年的频率进行。当一滴液体分裂成两个或多个单独的部分时，界面上出现的奇点的性质将用摄影技术来探测。观测将通过对纳维-斯托克斯方程进行详细的数值模拟来模拟。此外，还将模拟在各种地球物理环境中发生的模式(时间和空间)。非技术摘要：将进行一项研究，通过冷却液体来形成玻璃。我们将使用许多不同的光谱，并对它们进行比较。另一项研究关注的是一滴液体如何分裂成两个或两个以上的成分。这项研究将使用摄影技术结合详细的数值模拟来完成。最后，将继续进行一项研究，对地震和河流形成等各种地球物理环境中发生的模式进行模拟。***

9410478 Nagel Technical abstract: The relaxations in supercooled liquids will be investigated by means of different spectroscopic techniques including specific heat and dielectric spectroscopies, shear modulus and quadrupole susceptibility. The dielectric spectroscopy will be conducted over 14 decades in frequency. The nature of the singularity in the interface that occurs when a singlr drop of liquid splits into two or more separate sections will be probed using photographic techniques. The observations will be modeled with detailed numerical simulations of the Navier-Stokes equations. In addition, simulations of patterns (temporal as well as spatial) that occur in a variety of geophysical contexts will be simulated. Non-technical abstract: An investigation will be carried out by which glasses are formed by the cooling of a liquid. Many different spectroscopies will be used and compared to each other. Another investigation is concerned with how a single drop of liquid splits into two or more components. This study will be done using photographic techniques coupled with detailed numerical simulations. Finally, a study will be continued in which simulations are carried out of patterns that occur in a variety of geophysical contexts such as earthquakes and river formation. ***
