ABSTRACT:
A separator for removing water from a lower density liquid fuel has a generally circular cross-section container with co-axual downwardly open outlet conduit that includes a portion widening towards the bottom entry opening. An inlet above the widening portion of the conduit directs a liquid flow obliquely downwards and radially offset from the conduit to generate a rotational flow promoting separation of the denser water fraction from the fuel. Smaller water droplets that drift down the outer surface of the outlet conduit because they are less influenced by centrifugal forces, are collected in an upturned lip at the bottom edge of the conduit. There they coalesce into larger drops that can fall through the outlet flow to the bottom of the container. A shield in the container lower region limits the entrainment of remaining smaller droplets from that lower region into the outlet flow.
