As a sequel to our previous effort on the modeling of particle motion through a single lens or nozzle, flows of gas–particle suspensions through an integrated aerodynamic-lens–nozzle inlet have been investigated numerically. It is found that the inlet transmission efficiency (ηt) is unity for particles of intermediate diameters (Dp ∼ 30–500 nm). The transmission efficiency gradually diminishes to ∼40% for large particles (Dp > 2500 nm) because of impact losses on the surface of the first lens… CONTINUE READING
