Claim:
1. A method comprising: providing a centrifugal separator having an outer wall, surrounding a cavity and rotatable on a central shaft in rigid body motion therewith about a central axis, thereby defining length, radius, and circumference in, respectively, axial, radial, and circumferential directions and having an inlet end spaced axially away from an outlet end, and a heavy outlet and light outlet proximate the outlet end; introducing a flow into a conduit extending radially from the central shaft into the cavity proximate the inlet end; re-directing the flow toward the axial direction by modifying turbulent intensity of the flow along the radial direction by discharging through exits distributed radially, circumferentially, and each cut diagonally across its respective conduit; establishing a laminar, annular, velocity distribution (LAVD) in the cavity proximate the inlet end; the establishing the LAVD by reducing turbulent intensity of the flow moving axially along the cavity; the establishing the LAVD, wherein the reducing turbulent intensity comprises stripping eddy circulations occurring in non-axial directions.
