Specifically, the effects of gas superficial velocity on the sand transport in different pipe configurations and flow pattern development were investigated for a specified sand particle size and loading limit. Investigation was done using a two metre pipe length with physical model created in Gambit and computation implemented using Fluent 6.3. The results obtained showed that the gas phase promotes better sand transport. Specifically, increased gas superficial velocity led to an increase in sand particle transport in the cases considered and the gas phase affected the volumetric distribution of the entrained liquid phase during fluid flow. The results demonstrate that at a certain gas velocity, it is possible to attain critical sand carrying velocity relatively faster in a pipe flow system. %8 2013-06-11
