Critical and supercritical fluids have a variety of applications, from use as machine lubricants in high pressure or high temperature environments to the manufacturing of materials such as aerogel. The optical properties of fluids undergo rapid changes near the critical point resulting in a rapid increase in turbidity known as critical opalescence. These optical changes can be used to probe the universality of critical behavior. As a fluid approaches the critical point, the compressibility rapidly increases. In a gravitational field, this increase in compressibility leads to near-critical fluids stratifying by phase and density, making it difficult to observe the optical …

3d Imaging Of A Binary Colloidal Fluid, Kate Livermore, Michael Korth
Undergraduate Research Symposium 2019
In order to understand the nature of colloidal fluids, we wanted to visualize a 3D representation of their thermodynamic distribution. Colloidal fluids are fluids that consist of two parts: colloidal particles and a dispensing medium. Some examples include toothpaste, mayonnaise, plaster, and muddy water. We could also think about colloidal fluids simply as a mixture of two or more parts. In this poster, we used the hard-sphere system to represent the structure of colloidal fluids in a 3D graph using Mathematica (MMA). In the hard-sphere system, we used two different sizes of impenetrable spheres that could not overlap to represent …
