In this article, we extend the low Reynolds number fluid‐particle drag relation proposed by Yin and Sundaresan for polydisperse systems to include the effect of moderate fluid inertia. The proposed model captures the fluid‐particle drag results obtained from lattice‐Boltzmann simulations of bidisperse and ternary suspensions at particle mixture Reynolds numbers ranging from 0 ≤ Re mix ≤ 40, over a particle volume fraction range of 0.2 ≤ ϕ ≤ 0.4, volume fraction ratios of 1 ≤ ϕ i /ϕ j ≤ 3, and particle diameter ratios of 1 ≤ d i / d j ≤ 2.5. © 2009 American Institute of Chemical Engineers AIChE J, 2010
