Abstract
Drag coefficient and average Nusselt number are a critical operating parameters in fluid-particle processes. In this paper, a 3-D computational fluid dynamics (CFD) software is established to investigate the influence of the particle angle orientation on these parameters. A series of particles (spherical and non-spherical) has been developed and corresponding simulations are validated using correlations with reasonable accuracy. The results show that the average Nusselt number increases slowly with the particle angle orientation increasing from 0° to 30°, and rapidly when the angle orientation increases from 45° to 90°. The behavior gives high heat transfer, especially on the upper and front side of the cylinder when the gas velocity is high.
