| Summary: | Fluidized bed has been used in wide applications due to its capability to
provide a good mixing medium and heat transfer. It has been used and utilized for
many processes in industrial scale on various applications such as catalytic cracking
in the petroleum industry and gasification process in the energy industry.
The main focus ofthis work is to investigate a parameter for the fluidized bed
operating in a bubbling regimes; the effect of different orifice shape on fluidization
uniformity. For this purpose, Three (3) different orifice shapes were used, a classic
straight drilled hole perforated plate (cylindrical), a nozzle like shape (nozzle), and
also a diffuser like shape (diffuser). A numerical approach has been used to study the
hydrodynamic as it is more cost saving while capable of producing a result which
has a good agreement with the experiment results. |
