In the 1980s, statistical models, as an alternative approach, were used to calculate cyclone pressure drop. For instance, the models proposed by Casal and Martinez-Benet (1983) and Dirgo (1988) were developed through multiple regression analysis based on larger data sets of pressure drop for different cyclone configurations. Although statistical models are more …

The length of a cyclone is crucial factor that strongly affects both pressure drop and collection efficiency [6].Ideally, the length of the cyclone should coincide with the so-called "natural vortex length" (NVL) as it is closely associated with the process of particle separation [7, 8].A stable vortex can be maintained when the length of the cyclone matches the NVL [9, 10].
