ABSTRACT:
A turbulator for use with a fluid impelling device comprises a first side, a second side, and an apex toward which the first and second sides taper. The turbulator, circumferentially disposed about an inlet ring located adjacent the impelling device, is coaxially situated with an inlet passage of the inlet ring. The first side, second side, and apex define a triangular cross-section such that as laminar fluid flow from the second side moves over the apex of the turbulator, the laminar fluid flow is transitioned to a turbulent fluid flow on the first side prior to moving into the inlet passage. The turbulator also includes a plurality of evenly spaced slots for disrupting fluid flow symmetry within the inlet passage. The transition to turbulent flow and the disruption of fluid flow symmetry reduce acoustics as fluid is moved through the impelling device.
