A 2D model has been developed and meshed using Gambit software version 2.4.6 and was simulated using CFD code, fluent version 6.3. Laminar model has been used for the modeling and Eulerian-Eulerian multiphase model coupled with kinetic theory of granular flow was employed. For the drag, Gidaspow Drag Model was used to calculate the phase interaction between the gas and solid particles. The simulation results obtained for the validation purpose showed good agreement with the results available in the literature. The model with orifice plate gives a better and clear bubble shape with improved turbulent and better mixing compared to the model without the orifice plate. The model with orifice plate is also more realistic and ideal as compared to the model without the orifice plate. © 2012 American Institute of Physics. date: 2012 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84874166264&doi=10.1063%2f1.4757440&partnerID=40&md5=509dc410283877b681d6c9a7a6b126a3 id_number: 10.1063/1.4757440 full_text_status: none publication: AIP Conference Proceedings volume: 1482 place_of_pub: Kuala Lumpur pagerange: 69-74 refereed: TRUE isbn: 9780735410947 issn: 0094243X citation: Bin Ibrahim, M.H. and Mohd Najib, N.K. and Karuppanan, S. and Sinnathambi, C.M.
