Pneumatic conveying of solid materials is used in many process industries where solid
particles are carried forward in pipes and channels by the fluid. The pressure drop in the system is
dependent on a host of parameters such as particle and pipe diameters, particle and fluid
properties, pipe roughness and orientation, etc. In this study, the commercial CFD software,
STAR-CD is used to model pneumatic conveying in a horizontal pipe. A range of fluid flow rates
is studied. Reasonable agreement is obtained between the predicted pressure drop and the
experimental data of Marcus et al. (1990) for spherical particles and Vasquez et al. (2008) for
non-spherical particles. The sensitivity of the computed results to particle properties and the
choice of fluid drag model are also studied.
