Fluidized Bed
The fluidized bed phenomenon occurs when solid particles behave like a fluid. In this process, solid particles are placed in a closed environment, and gas is blown through them, causing the particles to become suspended and exhibit fluid-like behavior. For example, an object inside this chamber will experience a buoyant force.
ANSYS Fluent software has the ability to analyze, design, and optimize fluidized beds due to its capabilities in modeling fluid phenomena and heat transfer within these systems. All fluidized bed applications, including drying, particle coating, combustion, and chemical processing, can be simulated using ANSYS Fluent.

Heat Transfer
Heat transfer refers to the movement of thermal energy due to temperature differences, resulting in changes in temperature distribution and levels. Heat transfer is a crucial aspect of many industrial processes. To maintain the temperature within the desired range, it is essential to effectively manage the transfer and distribution of heat within a system. This can involve various mechanisms, including conduction, convection, and radiation, depending on the specific requirements of the process. Proper heat management ensures the efficiency and safety of operations, prevents overheating or excessive cooling, and enhances product quality. Techniques such as heat exchangers, insulation, and cooling systems are commonly employed to achieve optimal heat transfer in industrial applications.
