Fluidization is a process where solid particles are transformed into a fluid-like state by passing a gas or liquid through them. This occurs when the upward force of the fluid overcomes the weight of the particles, allowing them to move freely and behave like a fluid. This phenomenon is commonly observed in processes such as chemical engineering and pharmaceutical manufacturing. In fluidized beds, the solid particles are suspended in the fluid, enhancing mixing and heat transfer. This technique is widely used in various applications, including catalytic reactors and coal combustion, to improve efficiency and control reactions. Fluidization helps achieve uniform temperature and concentration throughout the system.
