“…The ηo and ΔP are the two most important parameters for determining the design and performance of a cyclone separator; these parameters are intimately related and affected by each other. In order to determine the optimum ηo must be a balance between the economics of operation, maintenance and the price of the separated material; in other words tradeoff between higher ηo and low ΔP across the cyclone is essential according to (Dirgo &Leith, 1985 andDemir et al, 2016). The maximum ηo and minimum ΔP were observed as aforementioned under the influence of air velocity, cone height, vortex finder length, dipleg length and the interaction between them.…”

A planar cyclone is designed for visualizing bubbles in the cross‐section of a degassing hydrocyclone. The pressure distribution is studied through a series of experiments and Reynolds stress model simulations. The velocity distribution of the planar cyclone mostly exhibits the quasi‐forced vortex zone and boundary layer zone. The bubble dynamics are simulated using both Euler‐Euler and Euler‐Lagrange approaches, and the output is compared with the imaging results. The Euler‐Euler simulation provides more accurate predictions of the bubble trajectory. The histograms of residence time and traveling distance given by the Euler‐Lagrange approach exhibit a reasonably regular pattern. With higher values of the inlet Reynolds number, stronger forces acting on the bubbles lead to a decreased but more uniform residence time. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2689–2701, 2018

Abstract. This article deals with a cyclone cleaner which separates solid particles from the gas. The influence of the input duct angle and the relation of the conical part of the apparatus to a cylindrical one on the cleaning degree were investigated. 3-d models of the flow channel of the opposite-flow cyclone with input duct angles varied from 0 to 40° and conical and cylindrical parts relation from 2:3 to 4:1 were considered. Numerical modelling of a soot clearing process in the opposite-flow cyclone was carried out in the ANSYS Fluent software. The results of 25 different models are presented.
