In this study, a cleaning device to remove micron-sized particles on a solid surface by an air jet is developed. This device has a special nozzle containing a triangular cavity to add high intensity turbulence to the air jet. Assuming that the spherical particles are removed by rotational movement, we estimated the rotational moment induced by drag force and local pressure gradient from calculated flow field by numerical simulation. This estimation for various nozzle shapes with different inlet widths revealed that the nozzle with 1.0 mm inlet width gives the best removal performance.
