1. A flow directing apparatus for directing fluid flowing therethrough, comprising:
- a flow body defining a bore therethrough configured and adapted to direct fluid flowing therethrough, wherein the bore includes an outlet and an opposed inlet with an enlargement configured and adapted to reduce sensitivity to entrance-edge conditions for the bore, wherein the enlargement of the inlet includes at least one of;
a countersink with a larger cross-sectional area than that of the bore downstream of the countersink; and
a chamfer having a depth corresponding to the square root of a cross-sectional area of the bore.

Abstract
A flow directing apparatus for directing fluid flow includes a flow body defining a bore therethrough configured and adapted to direct fluid flowing therethrough. The bore includes an outlet and an opposed inlet with an enlargement, formed as a countersink and/or a chamfer using a suitable boring device. The enlargement is configured and adapted to reduce sensitivity to entrance-edge conditions for the bore.

13. A flow directing apparatus for directing fluid flowing therethrough, comprising:
-
a flow body defining an inlet surface and an opposed outlet surface with a plurality of bores defined through the flow body from the inlet surface to the outlet surface, wherein each bore is configured and adapted to direct fluid flowing therethrough and includes an outlet and an opposed inlet with an enlargement configured and adapted to reduce sensitivity to entrance-edge conditions for the bore, wherein the enlargement of the inlet includes at least one of; a countersink with a larger cross-sectional area than that of the bore downstream of the countersink; and a chamfer that has a depth corresponding to the square root of a cross-sectional area of the bore downstream of the chamfer. - View Dependent Claims (14, 15, 16, 17, 18, 19)
