This paper reports the hydrodynamics of various Geldart Type-D particles when fluidized in a swirling fluidized bed (SFB). Four different sizes of particles ranging from 3.85 mm to 9.84 mm with respective densities ranging from 840 kg/m3 to 1200 kg/m3 were used as bed material to study the effect of various bed weights (500 gram to 2000 gram) and centre bodies (cone and cylinder) for superficial velocities up to 6 m/s. The performance of the SFB was assessed in terms of pressure drop values, minimum fluidization velocity, Umf and fluidization quality by physical observation on regimes of operation. The swirling fluidized bed showed excellent capability in fluidizing Geldart Type-D particles in contrast to the conventional fluidized beds. The bed pressure drop of increased with superficial velocity after minimum fluidization as a result of increasing centrifugal bed weight. It was also found that the particle size and centre body strongly influence the bed hydrodynamics. © (2012) Trans Tech Publications, Switzerland. date: 2012 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-81255171960&doi=10.4028%2fwww.scientific.net%2fAMM.110-116.3720&partnerID=40&md5=1539c2b52b8f88d94182bdf7b669b1cb id_number: 10.4028/www.scientific.net/AMM.110-116.3720 full_text_status: none publication: Applied Mechanics and Materials volume: 110-11 place_of_pub: Bangkok pagerange: 3720-3727 refereed: TRUE isbn: 9783037852620 issn: 16609336 citation: Mohideen, M.F. and Md Seri, S. and Raghavan, V.R.
