Abstract
A manifold with improved flow-splitting characteristics, resulting in uniform or nearly uniform flows from its outlet passages, is provided. The internal flow dynamics of the manifold are adjusted by modifying the cross-sectional area of the elongated manifold cavity. The cross-sectional area may be modified by placing one or more inserts in the interior cavity of the manifold, each insert having a nonconstant cross-sectional area designed to compensate for the differential flow characteristics within the manifold. Alternatively, the interior of the manifold may be formed with a nonconstant cross-sectional area designed to compensate for the differential flow characteristics within the manifold.
Claims6
A manifold for splitting the flow of a fluid, said manifold comprising:
- a main body with an elongated cavity of constant cross-sectional area perpendicular to a longitudinal axis of said main body, said cavity being longitudinally disposed between a first end and a second end of said main body;
- an inlet passage of constant cross-sectional area communicating with an interior of said cavity at a cavity inlet point;
- a plurality of outlet passages communicating with said interior of said cavity;
- and
- at least two inserts, a first insert extending longitudinally into said first end of said main body and a second insert extending longitudinally into said second end of said main body, said at least two inserts comprising a first leg and second leg being separated by a constant leg separation distance before meeting at a root, the first and second legs have a sloped surface constructed so that a cross-sectional area of each of said at least two inserts perpendicular to a longitudinal axis of each of said inserts varies in a manner that balances the volume of fluid that flows from each of said outlet passages.
