Swirling Fluidized Bed (SFB) is one of the systems that proposed vortexing to solid mixing due to a given gas source which impart on the solid mixing. This system is usually be used in the power generation, chemical industry, material production and drying processes. However, the used of blade distributor in SFB is still produced high-pressure drop even though it has been claimed the successful variant in fluidization systems. By using an annular blade distributor in a twist, the condition will cause in low-pressure drop and keep the energy consumption of a fluidized bed system in high efficient. The simulation study using Computational Fluid Dynamics (CFD) has been selected to investigate to the behaviour of velocity component and to determine the effects of the plenum chamber (axial entry) on airflow behaviour via twist blade distributor configurations. This study uses two (2) twist angle (80 and 100°) via several blade number 40, 50 and 60. Therefore low-pressure drop and high uniform velocity has be the main goal in this observation. The result of this study found that design on 100° twist angle via 40 number of blades distributor shows low a pressure drop besides being able to maintain the high airflow uniformity compared to other configurations.
