Particle trajectory in a pipe bend

This paper is an extension of previous paper by Salman et al., where numerical simulations of particle motion in a dilute horizontal pipe were carried out and variation of aerodynamic forces described. A bend was added to the pipe and numerical simulation compared with experimental measurements on the new geometry. It was found that the bend causes an increase in mean particle velocity compared with a horizontal pipe. Results show that the number of impacts in the bend decreases as the velocity of the particle increases. The results from the simulation agree closely with the experimental time-of-flight measurements.
