The design and choice of pipe fittings in such systems plays an important role as far as
headloss and flow separation are factors of concern. This study aims to investigate the flow
of coal water suspension through a converging section, diverging section and a bend using
computational fluid dynamics approach. The modelling and simulation are carried out on
geometries consisting of both converging and diverging sections of variable angles along
with a bend of R/d ratio of 2. The computational fluid dynamics simulation results are in good …
