A least investigated mesh-type distributor was used to fluidize the bed particles, at different air entry angles, for future applications in coating and granulation industry. A quarter of the bed was photographed using high speed imaging technique and the respective velocity fields of the swirling particles were produced using PIV technique. The Gaussian distribution of the particle velocity profiles was predicted at low superficial air velocity; particles near the border of the bed showed relatively low velocity than that swirled in the middle of the test section. However, at high superficial velocity, the particles near the central cone moved with velocity comparable to the particle velocity in the middle of the test section. Contrarily, the particles in the vicinity of the outer bed-wall maintained their steady state motion at all superficial air velocities. The average particle velocity experienced monotonic increase for more angular air intake. The magnitude of the particle velocity reduced by 6.35 for each 3 � increment in the air entry angle. © 2017, Springer-Verlag Berlin Heidelberg. date: 2017 publisher: Springer New York LLC official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85018911605&doi=10.1007%2fs10035-017-0727-4&partnerID=40&md5=9d107acb0c00c7f59836b52b3a809273 id_number: 10.1007/s10035-017-0727-4 full_text_status: none publication: Granular Matter volume: 19 number: 2 refereed: TRUE issn: 14345021 citation: Naz, M.Y. and Sulaiman, S.A. and Shukrullah, S. and Ghaffar, A. and Khan, Y. and Ahmad, I.
