Digital simulation on optimization of number of tangential inlets of gas-liquid cyclone

The internal flow field in gas-liquid tangential cyclone with multiple inlets was studied by numerical simulation based on RSM model and DPM model provided by FLUENT software,and the distribution and pressure drop of flow field of gas phase as well as variation of separation efficiency were studied while the cyclone having various number of tangential inlet. The results showed: the symmetrical inlets were conducive to the formation of symmetrical flow field; while remaining inlet velocity constant,the pressure drop increased slightly with the increase in number of inlet,although separation efficiency altered greatly; while the number of inlet being two,the separation efficiency was the maximum,the pressure drop was a few more than that of the single inlet; while the number of inlet being more than two,the separation efficiency decreased remarkably.
