👉 The Cohen fluid, also known as the Cohen gas or the Cohen liquid, is a theoretical supercritical fluid that exists at extremely high pressures and temperatures, typically above 30 MPa (or about 430 bar) and 600-700°C. Unlike conventional liquids or gases, it exhibits properties of both states, behaving as a fluid with high density and viscosity similar to liquids, while also possessing the diffusivity and compressibility of gases. This unique combination makes it an intriguing subject in research for applications such as enhanced mass transfer, chemical reactions, and energy storage. The Cohen fluid's behavior is so extreme that it challenges our conventional understanding of phase transitions and fluid dynamics, offering potential advancements in various scientific and industrial fields.
