Effect on the Separation Efficiency of Swirl Tubes

Much less experimental data are available on the effect of solids loading on the separation efficiency of swirl tubes with swirl vanes. If the effect of solids loading is indeed one taking place in the inlet region of tangential inlet cyclones, we might expect it to be quite different in devices with swirl vanes. 

This turns out to be so. Experimental data obtained in the laboratories of the writers show a clear difference between the effect of loading in the two types of device. The evidence is scant, however, and will not be reported at this stage. 

There are no models in the open literature for computing the effect of solids loading on swirl tube efficiency. The best approach for doing this in the first instance may be to fit the exponent a in a relationship of the Smolik type
