Numerical calculation of the thermal conductivity of two regular bidispersed beds of spherical particles

A mass transfer correlation for packed bed of lead oxide spheres in flowing lead–bismuth eutectic at high Péclet numbers

“…It is known from previous studies that the Sherwood number for packed bed geometries is influenced by the channel-to-particle diameter [30][31][32][33][34][35], especially for low values of R. A small R configuration is more likely characterized by channeling and preferential flow patterns, which might influence the overall dissolution rate.…”

“…Extensive work was performed in the past to understand mass transfer behavior in packed beds at low-R. According to Tsodas [34,35], rather axial dispersion than radial flow maldistribution (channeling) has an influence on the overall efficiency of particleto-fluid mass transfer in narrows packed tubes. Martin [36], on the other hand, attributes the difference between experiments and calculated Sherwood number to channeling effects and mixing in the voids.…”
