A procedure has been developed at the MIKhMe for the design of a hollow cyclone separator with a rectangular tangential inlet of the gas-liquid mixture near the bottom. The procedure is based on the results of theoretical and experimental investigations of the cyclone and allows one to determine the geometrical dimensions and the operating ...

In this paper, the separation performance of the axial-flow oil–water separator for five design variables (conical diameter, conical length, number of vanes, angle of vane, and thickness of vane) was analyzed. Numerical calculations for multiphase fluid were performed using the mixture model, one of the Euler–Euler approaches.

Cyclone separator is a method of removing particulate from an air, gas or liquid stream without the use of filters, through vortex separation. Rotational effects and gravity are used to separate mixtures of solids ands fluids. ... The cyclone design procedure outlined in Cooper and Alley (1994), hereafter referred to as the classical cyclone

Abstract A model was proposed for determining the efficiency of fractional separation in a uniflow cyclone. The model includes parameters that characterize the motion of a particle in the cyclone and, hence, the degree of separation, namely, the distance that the particle travels when moving in a helical path, and this path itself. The …

The collection efficiency of cyclones varies as a function of particle size and cyclone design. Cyclone efficiency generally increases with (1) particle size and/or density, (2) inlet duct velocity, (3) cyclone body ... axial discharge; axial inlet, axial discharge; tangential inlet, peripheral discharge; and axial inlet, peripheral discharge ...

Types of cyclones used for filtering the intake air in motor vehicles: (a) reverse-flow cyclone (b) return with axial inlet, (c) axial flow (vortex tube separators). In a reverse cyclone, the gas stream, after reaching the bottom of the cone, turns into a backward helical movement upwards and flows out through an outlet pipe made centrally

In comparison to Stairmand cyclone and gas–liquid cylindrical cyclone (GLCC), few works are available on the design and modeling of the axial flow cyclone separator. Wedding et al. (1982) proposed a dichotomous sampling head using an axial flow separator design to match the human thoracic penetration curve.

The most common type of cyclone separator is the tangential inlet, axial discharge style shown in Figure No. 1. The second often-used design is the axial inlet, axial discharge type which uses slanting vanes to start the air spinning. The tangential inlet cyclone covers a much larger range of throughput and particle sizes than the axial inlet ...

There are two major criteria for the performance evaluation of cyclone separators: particle collection efficiency and pressure drop. It is desirable to improve particle efficiency without increasing pressure drop. In this study, a counter cone was installed inside an axial cyclone is investigated. It was found that the d/B (ratio of the …

The uniflow cyclone or axial cyclone, is a interesting alternate design, which is able to deliver comparable efficiencies in a very compact geometry. The name is derived from the flow field pattern generated inside the cyclone. Unlike reverse flow cyclone, the gas enters and leaves the cyclone in the same direction (see Figure 1).

In order to build a more stable flow field structure in the traditional axial flow vane-guide cyclone separator, a new type of cyclone is designed by inserting an expanding section between the cylinder and the particle exit tube. Experimental results show that the separator has a separation efficiency of over 80 percent for fine particles which …
