Fluidized System

In this study, a three-phase (gas-liquid-solid) fluidized bed was used to study the heat transfer characteristics of the system. The system consisted of low density (290 kg/m3) spherical particles of the diameter of 2 cm in 0.25 m cylindrical column with the countercurrent flow of water and air. The experimental investigation and mathematical modeling of heat transfer between the hot air and the cooling water was carried out. The experiments were conducted for the variety of different fluid flow rates and inlet air temperatures, while the air flow rate was kept constant. Based on the obtained experimental results a new correlation for heat transfer in three-phase fluidized system was proposed. The mean percentage error between the experimental and the correlated values of the jHp obtained was 1.69%. The hydrodynamic parameters of the system were also calculated according to the available literature correlations.
