A Predicting the Effect of Solids Loading on Cyclone Efficiency

A Predicting the Effect of Solids Loading on Cyclone Efficiency 

As mentioned in the main text, one strategy for calculating the performance of a cyclone at elevated loading is to calculate the working of the cyclone or swirl tube at low loading, and then calculate the effect of solids loading afterwards. 

Let us try to predict the effect of loading on the efficiency of the cyclone in Fig. 9.1.1. All the data we need are in the figure legend. We start by calculating the Muschelknautz critical load, Eq. (9.1.1)  

We also need vom = v0wV0xy - This is more of a problem. To be consistent and adhere to the Barth-Muschelknautz approach, we should use Eq. (4.2.4) to calculate vow and Eq. (4.2.6) to find vox, which is the same as vcs- However, this seems quite cumbersome if we only want to estimate the effect of loading on efficiency.  

To speed up the process we can take as being roughly equal to the inlet velocity, and we can obtain vqx from the n-law, Eq. (4.2.2) using a reasonable value for n of 0.8. Doing this for the inlet velocity of 15 m/s, and first substituting the known value of vq dit r = (D/2) to find the constant C, we get
