ABSTRACT: The carrier fluid (air or water) is used to
transport solid material from the source place to its destination point through
pipeline. Using air as carrier fluid to transport solid material through
pipeline is called Pneumo transport, whereas transporting material with water
or any other liquid through pipeline is called as hydraulic transport. A large
number of installations are now available globally to transport solid materials
to short, medium, and long distances using water/air as carrier fluid. However, the design of such system of pipeline is still an empirical art. In the
present investigation, one generalized mathematical model developed by
Shrivastava and Kar (SK Model) and CFD models
were used and compared with experimental results for pneumatic and hydraulic
transport of granular solids. The motivation of present work is to find
the accuracy of SK model based on analytical, empirical and semi-empirical for the prediction of pressure drop and
comparing the result with CFD based on mathematical equation for the mixture
flow in the horizontal and vertical pipe lines. The comparison of pressure drop
results obtained by using SK model
and CFD model were validated with the experimental results for pneumatic and
hydraulic transport of solids through. From the comparison results, it was
observed that the results of pressure drop predicted by SK model are
more accurate than the CFD models for all the cases considered.
