Hydrodynamics Analysis of Quadrilobe Catalyst by CFD Simulation

In this paper, drag coefficient of infinite quadrilobe catalyst with non-circular cross sections has been investigated by Computational Fluid Dynamics (CFD) methods and for this purpose FEMLAB Multiphysics V2.3 and finite element methods are used. Influence of different number of particles (single, two, three and four particles) and oriented angle of particles on drag coefficient have been investigated. Model validation has been done with comparison of reported experimental data and CFD simulation results for infinite cylinder. The drag coefficient results for cross flow on infinite quadrilobe particle shows a significant difference with cylindrical particle. With increasing of Reynolds number, the drag coefficient significant difference with cylindrical particle.
