Swirling Fluidized Bed (SFB) is one of the potential fluidized systems that has introduced a liquid-solid interaction system. SFB system is widely used in the power generation, chemical industry, material production and drying processes. Inside the SFB, there is ring-shaped annular blade distributor and it works is to give the best fluidization performance. The efficiency of a fluidized system depends on the distributor's design and the inclination of gas injection. The simulation study was conducted using Computational Fluid Dynamics (CFD) package GAMBIT 2.4.6 and FLUENT 6.3.26 software to obtain the result of velocity distribution and pressure drops on various blade distributor designs. This study uses two (2) twist angle blade distributor design types. The twist angles are 80° and 100° with the number of the blade distributor are 40, 50 and 60. The main component of the velocity analyzed in the fluidized system are tangential velocity, radial velocity and axial velocity. Fluidization is caused by axial velocity while the rotating effect causes by tangential velocity. In this study, tangential velocity is the main velocity component because the velocity represents the rotating air velocity in fluidized system. The centrifugal force of the spinning gas produces the radial velocity. Additionally, the performance of pressure drop and uniform velocity was measured and evaluated. The best results and findings of this simulation study are the design of the twist angle distributor gives the lowest value of pressure drop compared to previous studies. Overall, the design of the 100° twist angle and 40 blades distributor are the best distributors of blades compared to others.
