Different contours (for inlet velocity 0.81 m/s): (a) Static pressure, (b) Tangential velocity, (c) Particle tracks- Particle trajectories reveal cyclonic motion, with heavier particles collected at the underflow and lighter particles exiting through the overflow, (d) Velocity streamlines- Swirling flow patterns highlight the interaction between the inner and outer vortices, both rotating counterclockwise.
