When a fluid passes through a conventional elbow or valve in a piping system, turbulence is created in the fluid flow. The fluid may not stabilize and return to a laminar flow until 40-50 pipe diameters downstream. Turbulence in a piping system can cause a variety of problems such as noise, vibration, and/or erosion. Turbulence also creates a pressure drop which is undesirable. The flow diffuser of the present invention may be configured as a 90.degree. elbow for use in a piping system to reduce turbulence and pressure drops as the fluid passes through the improved elbow. The elbow of the present invention included an elongate tapered discharge nozzle. The elbow can restore substantially laminar flow in a space of about four pipe diameters.

[ What is claimed is:] [1.]1. A diffuser connected to an inlet conduit and an outlet conduit to reduce turbulence as fluid flows from the inlet conduit through the diffuser to the outlet conduit comprising:a body defining an inlet and an outlet;a removable flow conditioner having a top, a bottom, an inlet port in said bottom, and a side wall joining said top surface and said bottom surface, the side wall extending at least 180.degree. about the removable flow conditioners including:said inlet port having a diameter at least equal to the diameter of said inlet, there being fluid communication between the inlet conduit, said inlet and said inlet port;an outlet port defined by said side wall, said top and said bottom;an inlet zone having an area at least twice the cross-sectional area of said inlet port, there being fluid communication between the inlet conduit, said inlet, said inlet port, and said inlet zone;a protrusion extending from said top into said inlet zone;a plurality of stationary guide vanes defining a plurality of curvilinear passageways, each passageway having a beginning in fluid communication with said inlet zone and each passageway having an end in fluid communication with said outlet port, each of said vanes extending from said bottom to said top of said removable flow conditioner;each of said curvilinear passageways having a cross-sectional area at said beginning that is at least twice as large as the cross-sectional area at said end;a transition zone defined by said body, said transition zone in fluid communication with said outlet port of said flow conditioner;an elongate tapered discharge nozzle including:an elongate tapered interior surface defining a discharge passageway with a generally rectangular shaped inlet and a circular outlet, said rectangular inlet in fluid communication with said transition zone and said circular outlet in fluid communication with the outlet conduit;said discharge passageway having a length at least twice as long as the diameter of the inlet; andsaid discharge passageway having a generally constant cross-sectional area.
