B Predicting the Effect of Loading on Cyclone Pressure Drop

B Predicting the Effect of Loading on Cyclone Pressure Drop 

Four models predicting the effect of loading on pressure drop were mentioned in the main text the empirical relations of Smolik, Briggs and Baskakov, and 

We first apply the Smolik equation to the results shown in Fig. 9.1.5 in the main text. This relation can be applied directly. For instance, we find that the pressure drop at zero load, Apo, is about 430 Pa for an inlet velocity of 10 m/s, so at this inlet velocity  

Admittedly, simply curve-fitting the data provides little insight into the underlying mechanisms relating pressure drop to inlet velocity or solids concentration. Even so, such a data regression allows us to express the data in a very efficient equation format suitable for machine computations and for interpolation purposes. 

In Fig. 9.B.2 we have replotted the experimental results of Gil, Romeo and Cortfe (2002) together with the models of Smolik (9.1.6), Briggs (9.1.7) and Baskakov et al. (9.1.8). It is possible to plot the model equations of Smolik and Briggs directly on an x-axis of Co, by rewriting them, substituting for c by realizing that c = Co[kg/kg] x p[kg/m ] x 1000[g/kg].
