| Abstract: | Pressure drop across a 90° horizontal bend for fly ash slurry at high concentrations is
reported in the present study. The pressure drop across the bend has been
measured at five concentrations in the range of 50-65% (by weight) and the data
has been analyzed to obtain the relative pressure drop, bend loss coefficient
and permanent pressure loss. Measurements show that the relative pressure drop
across the pipe bends increases with increase in concentration at low velocity.
However, at any given concentration relative pressure drop is independent of
velocity over the range tested. The bend loss coefficient at any velocity
increases with increase in concentration. The permanent pressure loss increases
marginally with concentration and velocity. The contribution of disturbed flow
conditions downstream of the bend to the total pressure loss is much less in
the case of highly concentrated slurries as compared to that in water. |
