Twist Blade Distributor in Fluidization Systems: Part 2 – The Air Flow Characteristics

This study examines the findings of numerical analysis studies that were conducted to determine how the arrangement of the blade distributors in a fluidization system affects the distribution of air flow distribution. In contrast to the conventional methods, which give the particle a swirling motion, the current fluidization systems produce a circular movement of a beds. Therefore, the influence of twist angle blade (60° and 100°) was investigated through to the horizontal inclination angle (15°) and radial inclination angle (10° and 12°) blade distributors. In a fluidization systems, the simulation was used to calculate and assess the performance outcomes of three velocity components: tangential velocity, axial velocity, and radial velocity. These components represent the flow of fluid inside the plenum fluidizations systems. According to the results of the numerical study that used a horizontal inclination of 15°, the velocity of the airflow in the fluidization systems may reach up to 8 m/s. This circumstance occurred because the air flow was quite near to the large opening area where the airflow was allowed to enter. This is due to the less of an interruption to the airflow when it enters the gap area between the two blades distributor.
