👉 The Cz fluid, also known as the Cz fluid model or the Cz model, is a theoretical framework used in soft matter physics to describe the behavior of complex fluids with long-range interactions and spatial heterogeneity, such as colloidal suspensions or polymer solutions. It extends the traditional fluid dynamics by incorporating the effects of long-range attractive and repulsive forces between particles, as well as spatial variations in particle concentration or interactions. The model uses a combination of mean-field approximations and statistical mechanics to predict macroscopic properties like viscosity, diffusion, and phase behavior. By accounting for these intricate interactions, the Cz fluid provides a more accurate description of real-world soft materials compared to simpler models that assume short-range interactions or neglect spatial variations.
