Description

A numerical simulation was carried out to study the resistance characteristics of single-phase isothermal flow in rectangular channels with two-dimensional regular packing of spherical particles using CFX 10.0. Simulated pressure drop of different turbulence models (Standard k-ε model, RNG k-ε model and SST model) were compared with the predicted values of Ergun's equation. Particle packing style and particle diameter were considered as the important factors with effect on flow resistance in this paper. Besides, the pressure drop and drag coefficient variation trends were obtained when Reynolds number was in the range of 1.5∼1497. (authors)
