Abstract: A numerical simulation study for flow behavior of sulfur slurry in 135° bend pipe has been conducted by Eulerian-Eulerian model. Validation of the models could be obtained from the comparison with a 90° elbow of Toda. The predicted results were in good agreement with experimental data. A general comparison of pressure drop in the 45° and 90° elbow were also discussed in present research at the same operating condition as a reference. The effects of the sulfur slurry volume fraction and sulfur slurry velocity on the pressure drop in elbow as well as on the flow characteristics in 135° bend were studied. In present research, when the sulfur slurry volume fraction was 0.15, the minimum transport velocity was proposed to be higher than 1.2 m/s.
