Performance analysis in square cyclones using Sobol statistical sensitivity analysis method

Cyclones are devices used to separate two or more phases from each other. Cyclones are centrifugal particle collection systems that use the effect of a tornado to separate solid particles from the gas stream. The purpose of this article is to investigate the effect of 5 inlet parameters including inlet height, inlet width, outlet diameter, total cyclone height and body cyclone height on both pressure outlet and cut-off diameter. These parameters have not yet been investigated by Sobel analysis. In this article, the effect of 5 cyclone inlet parameters including inlet height, inlet width, outlet diameter, total cyclone height and cyclone body height on two outlet parameters including pressure drop and shear diameter was investigated through their regression equation and Sobel statistical sensitivity analysis. So far, the effect of these 5 parameters on these outputs has not been investigated through Sobel statistical sensitivity analysis. The results show that inlet width with 40%, inlet height with 36% and outlet diameter with 24% had the greatest effect on pressure drop, respectively, and the height of the cyclone and the square height of the body had no effect on pressure. On the other hand, the inlet height with 40%, the inlet height with 38%, the height of the cyclone with 12% and the body height of the cyclone with 10% have the greatest effect on the shear diameter, respectively, and the cyclone outlet diameter has no effect on the cut-off diameter.
