Product Details

This apparatus is designed to demonstrate the principles of fluidization, allowing students to observe the transition of a granular solid from a fixed bed to a fluid-like state when a fluid is passed upward through it. It is used to study the characteristics of fluidized beds using both air and water as the fluidizing medium and to verify fundamental equations like Carman-Kozeny and Ergun. The unit consists of two removable, graduated tanks that hold the granular material. A water circulation pump and a compressed air supply with an adjustable valve provide the necessary fluid flow. A manometer is connected to measure the pressure loss across the bed as the flow velocity increases, enabling the observation of the minimum fluidization velocity and the relationship between bed expansion and flow rate. Its primary application is in chemical and process engineering education for teaching unit operations involving solid-fluid interactions. The key benefit is the clear visualization and quantitative analysis of the fluidization process, enabling students to understand the dynamics of fluidized beds used in industrial applications such as reactors, dryers, and combustors.
