👉 A sandy fluid, also known as a granular fluid or granular fluid, is a non-Newtonian fluid composed of fine particles suspended in a liquid medium. This suspension gives the fluid its unique properties, where the viscosity can change in response to applied stress or shear rate. When a force is applied, the particles rearrange and form temporary bonds, increasing the fluid's resistance to flow. Conversely, when the force is removed, these bonds break, allowing the particles to slide past each other and reducing viscosity. This behavior is observed in materials like quicksand, where the fine sand particles create a highly viscous environment, and in industrial applications such as drilling fluids, where maintaining stability under varying pressures is crucial.
