A New Correlation For Drag Coefficient of Extrudate Quadralobe Particles By Cfd Simulation

In this paper, drag coefficient of infinite quadralobe catalytic particle with non-circularcross sections has been investigated by computational fluid dynamics (cfd) methodsand for this purpose femlab multiphysics v2.3 based on finite element methods havebeen used. a new simple correlation for drag coefficient of infinite quadralobe particlehas been established over the range of reynolds numbers from 0.01 up to 1000.acomparative study has been made between the numerical results of this study and theavailable data in the literature. the predicted drag coefficient of infinite cylinder showsgood agreement with experimental data within a converging quantitative error of lessthan 7% up to reynolds number of 1000. the drag coefficient results for cross flow oninfinite quadralobe particle shows higher value in comparison with cylindrical particle.in addition, influence of different number of particles (single, two, three and fourparticles) and orientation angle of particles on drag coefficient have been investigated.
