Sep 06, 2017 · In this paper, a Phenomenologicalbased Semiphysical Model (PBSM) is developed to predict the behavior of hydrocyclones. The developed model is based on physical principles but considering the compromise between accuracy and computation, allowing the use of the model in real time operation. The model contains 92 nonlinear algebraic equations, .
particle particulate or diameter: P drop = pressure drop: Q = gas flow rate: P = absolute pressure: p gas = gas density: u = air viscosity: u gas = gas viscosity: K = proportionality factor: T = temperature: v = settling velocity: S = separation factor: N = approximate effective turns: h = inlet height: L cylinder = cylinder length: L cone ...
The size and shape of the vortex finder, the shape, of the chamber into which the feed liquid is injected and the geometry of the feed inlet all dictate the details of the flow pattern which will often include recirculatory streams (see Figure 5).. Due to this complexity many authors have produced correlations for both the separation efficiency and the pressure drop in hydrocyclones.
