1D3D and 2D2D cyclones were tested at Amarillo, Texas to evaluate the effect of air density on cyclone performance. Two sets of inlet design velocities were used for the tests one set based on the actual airflow and the other set based on standard airflow. Experimental results indicate the design velocities are 3200 feet per minute of standard air for 1D3D cyclone design and 3000 feet per minute of standard air for 2D2D cyclone design. It is important to consider the air density effect on cyclone performance in the design of cyclone abatement systems. The proposed design velocities should be the basis for sizing cyclones and determining the cyclone pressure drop. The recommended sizes for 1D3D, 2D2D and 1D2D cyclones are reported in this paper.
