A three dimensional numerical study of flow characterized of fly ash - water slurry in a horizontal 180 ̊ pipe bend having radius ratio of 5 .6 is described in this paper. The flow constitutes the fly ash particles of size 13 μm in water at velocities ranging between 1.0 - 5.0 m/s and particle concentrations ranging between 10 - 50% by volume for each velocity of flow. The numerical simulation is c arried out by deploying the Eulerian Multiphase Model of CFD code in ANSYS Fluent code. The results illustrate that the overall pressure drop is 62% in the pipe bend at all particle velocities and concentrations. The velocity and concentration distribution s at various positions (0 ̊, 90 ̊ and 180 ̊) of the bend were illustrated.
