The effect of the effective parameters such as the applied voltage of the DBD plasma actuator, the arrangement of plasma actuators, the velocity of the incoming flow of the cyclone, and the size of solid particles are evaluated. The results show that the separation performance of the cyclone in the presence of the DBD plasma actuators increases in all particles with different diameters between 1 and 2 mm, compared to the cyclone without the presence of plasma actuator, and the performance enhancement is higher in the particles with a larger diameter (2 mm). The arrangement of plasma actuators has a significant effect on the particle separation performance of the cyclone, and the uniform installation of plasma actuators in the entire height of the cylindrical part of the cyclone (type one arrangement) improves the particle separation performance compared to other arrangements. The results show that the use of the DBD plasma actuators inside the cyclone can increase the cyclone separation performance by 26.5% compared to the cyclone without the DBD plasma actuator.</span> <span style="letter-spacing: -.1pt;">In this paper, the effect of secondary flow induced by the DBD plasma actuators on the flow and separation performance of solid particles in a cyclone is numerically investigated.
