Abstract

In the present study, the technique of combining asymptotics with computational fluid dynamics (CFD), called the asymptotic computational fluid dynamics (ACFD), has been used to obtain a correlation between pressure drop coefficient and the number of pipe inlet into the plenum chamber of a swirling fluidized bed based on CFD results obtained by Othman [2010]. Othman [2010] investigated the influence of various inlet types and hub designs as well as the introduction of multiple inlets on the aerodynamic behavior in the plenum chamber of a swirling fluidized bed. The final design chosen was the four radial offset (R/2) air inlets into the plenum chamber containing a full length cylindrical hub. This design offers a balance in the required performance characteristics, thus leads to optimum performance of the fluidized bed. The obtained correlation provide a full range of CFD results without actually carrying out the entire set of calculations. This powerful tool is still very rarely applied, especially in Malaysia. Therefore this study has provided a significant benchmark of ACFD study for fluid flow.
