Abstract

This paper presents numerical analysis studies to identify air flow distribution affected by various blade distributor configurations in a swirling fluidized bed (SFB). The SFB is in contrast with conventional that impart swirling motion to the particle. The study focused on the effect of spiral blade distributor configuration where by the effect of various pitch length (60 mm, 80 mm and 100 mm) via various horizontal inclination angle (0°, 12° and 15°). The simulation was applied to compute and evaluate the performance results of velocity magnitude in an SFB. Moreover, the new types of the annular spiral blade had less to reduce the power being wasted during the processes. The numerical analysis with the parameter of horizontal blade inclination of 0° through all pitch length configuration of spiral blade distributor has shown that the air flow in SFB rise until 40 m/s. This condition is due to the air flow was very close to the SFB entry space. The flow of air entering the area between the two blades is not much flow disturbance
