CFD study of fluid flow and wall heat transfer in a fixed bed of spheres
TL;DR: In this article, the relationship between the local flow field and the local wall heat flux in a packed bed of spheres was investigated and it was shown that local heat transfer rates do not correlate statistically with local flow fields.

CFD modelling and experimental validation of particle-to-fluid mass and heat transfer in a packed bed at very low channel to particle diameter ratio
TL;DR: In this article, the mass and heat transfer characteristics of a composite structured catalytic reactor packing (Composite Structured Packing) are investigated, and the constants of the commonly used engineering correlation Nu = c 1 + c 2 Re n Pr 1/3 were obtained by fitting the CFD results for N = 1.00, 1.15,1.47, 2.00
