Abstract

Cooling towers are heat extraction devices used to provide a constant supply of cold water in industries such as petrochemicals, food processing, dairy, power plants, and nuclear power plants. The heat exchange phenomena in cooling towers are a direct contact phenomenon that involves simultaneous heat and mass transfer. The papers for the numerous methods of Fluidized bed packing that are incorporated for the conventional cooling tower are reviewed in this study. The cooling tower's packing enhances the effective contact surface between air and water, allowing for more efficient heat and mass transfer. The fluidization principle is used in the design of a fluidized bed cooling tower. The upward flow of air fluidizes the bed material employed as packing in the three-phase counter flow fluidized system, and the hot water sprayed down from the top is cooled. The report also goes through the various materials that are used in the fluidization process. As the gas and liquid phases flow through the bed, the weather will cause a bubbling or turbulent effect that gives a larger surface area for heat transfer, resulting in a state of strong contact between them. The major goal of this literature analysis is to look at how different scholars have analyzed the performance of cooling towers with fluidized bed packing, which will lead to additional research. Furthermore, it is discovered from these studies that various investigations are conducted at low water flow rates and also at lower liquid to gas ratios, which leads to the research of cooling tower performance by providing the turbulent bed and experimental conduct at higher flow rates.
