Cyclone calculation

This example shows how to use the software Cyclone to calculate a cyclone. With a few known parameters, the software will calculate the unkown parameters, like the cyclone dimension and the efficiency for different particles size.

Known parameters

air flow rate: 3 m3/s

pressure: 1 bar

gas is air at room temperature: 293 °K

solid density is : 1500 kg /m3

solid distribution is:

particule diameter (micron) inferior cumulated frequency
8 0.07
12 0.13
24 0.3
32 0.5
48 0.86
64 0.94
78 0.99
96 1

overall efficiency should be: 0.92

Parameters to calculate

cyclone dimension

efficiency depending on the particule size

pressure drop in the cyclone


Step 1. Enter the gas parameters Step 2. Enter the solid parameters
Step 3. Choose an included geometry or entry your own geometry Step 4. Choose the known variables combination
Step 5. Choose a model in the list. Here the simualtion has been made with the Lorenz model. Eventually it is possible to enter a particule diameter distribution to calculate the efficiency for every particule size class (not possible with the Barth model).

Then press the simulation button.

The software give you in this case the cyclone dimension, the cut diameter and the pressure drop.

Cyclone calculation

The efficiency for every particules size is available in the parameters window.


With the software Cyclone, you can easily calculate the dimension of a cyclone, without to enter one formula. The software calculations are very quick wich allow you to compare different cyclone parameters in a short time.
