Fig. 5.

Histogram of particle travel average speed distribution for all particles released in the system for the 9 different particle masses. Panels on the left (a, c, e) are core release cases while panels on the right (b, d, f) are near-wall release cases. In curve labels: A, B, C representing particle density of 800, 1,050, 1,300 ${\text{kg/m}}^3$; number 1,2,3 representing particle diameter of 200, 500 and 800 $\mathrm{\mu }\text{m}$ as defined in Table 2
