<p>A particle separator (110/210) which broadly comprises: an inner wall (116/216), an outer wall (114/214) and a splitter (118/218), wherein the inner (116/216) and outer (114/214) walls define an intake passageway (124/224), and wherein the splitter (118/218) is positioned between the inner (116/216) and outer (114/214) walls so as to define a scavenge airflow passageway (138/238) connected to the air intake passageway (124/224) and a main air flow passageway (110/210) connected to the intake passageway (124/224); the inner wall (116/216) having a humped-shaped portion (146/246) between the intake passageway (124/224) and the main air flow passageway (1/210); the humped-shaped portion (146/246) having a peak (150/250) and a radius of curvature at any point on the hump-shaped portion (146/246) of the inner wall (116/216) after the peak (150/250) corresponding to a degree of curvature of from 30 to 60 degrees; and a boundary layer control mechanism (292/294, 296/298) for providing active boundary layer control along the inner wall (116/216) after the peak (150/250) and within the main air flow passageway (130/230). Also provided is a method for providing active boundary layer flow control along the inner wall (116/216) after the peak (150/250) and within the main air flow passageway (130/230).</p> |
