👉 Fluid refers to a type of fluid that is particularly known for its unique and versatile properties, often used in various industrial applications. Unlike traditional liquids, fluid exhibits both liquid-like and gas-like behaviors depending on external conditions such as pressure and temperature. This dual nature allows it to flow like a liquid while also expanding like a gas, making it highly adaptable for use in processes that require precise control over volume and pressure. Common applications include fluidized beds in chemical processing, where solid particles are suspended in an upward-flowing gas stream, creating a fluid-like state that enhances heat and mass transfer efficiency. Fluid's adaptability also makes it useful in filtration systems, where it can change its state to trap or release particles based on environmental conditions.
