• Diffuser (thermodynamics) — A diffuser is the mechanical device that is designed to control the characteristics of a fluid at the entrance to a thermodynamic open system. Diffusers are used to slow the fluid s velocity and to enhance its mixing into the surrounding fluid.… …   Wikipedia

• diffuser — A specially designed duct, chamber, or section, sometimes equipped with guide vanes, that decreases the velocity of a fluid, such as air, and increases its pressure, such as in a jet engine, a wind tunnel, etc. In a gas turbine engine, the… …   Aviation dictionary

• diffuser vane — A turning or cascading vane in a centrifugal flow engine diffuser used to change air direction from radial, as it leaves the impeller, to axial, as it enters the combustors. Diffuser vanes assist in converting velocity into pressure. Double entry …   Aviation dictionary

• Mixed flow compressor — For more details on this topic, see Centrifugal compressor. A mixed flow compressor combines the axial and radial components to produce a diagonal flow unit. The exit mean radius is greater than at the inlet, but the flow tends to exit in an… …   Wikipedia
