Abstract
ABSTRACT
The effect of the cyclone height (both the barrel and cone) on the performance and
flow field pattern has been investigated computationally for six cyclone separators.
The results show that the maximum tangential velocity in the cyclone decreases with
increasing the cyclone (barrel or cone) height. Increasing the barrel height makes a
small change in the axial velocity, whereas increasing the cone height changes it
considerably. Increasing the cyclone (barrel or cone) height decreases both the
pressure drop and the cut-off diameter. The changes in the performance beyond h/D
= 1.8 (Ht/D = 4.3) are small at constant cone height, whereas the performance
improvement stops after hc/D = 4.0 (Ht/D = 5.5) at constant barrel height where h is
the barrel height, hc is the cone height, Ht is the total cyclone height and D is the
barrel diameter. The effect of changing the cone height on the flow pattern and
performance is more significant than that of the barrel height.
