WebDIFFUSER: Diffusers are flow passages just like nozzles, except that they cause a rise in static enthalpy and hence pressure, at the expense of kinetic energy. The equations for an ideal nozzle (ηn=1) apply equally well to an ideal diffuser, except that in practice diffusers are rather inefficient devices compared to nozzles. WebNozzles are used in steam and gas turbines, jet engines, rocket motors, flow measurement, etc. When a fluid is decelerated in a duct it is called a diffuser. Diffusers are used in …

WebThe diffuser, as a divergent duct, converts the maximum part of the velocity component of the flowing air into static pressure. This effect results in a point of highest static pressure and lowest velocity in the entire engine where the outlet of the diffuser and the inlet of the combustor meet. WebNozzles are steady flow engineering devices that are used to increase a fluids velocity at the expense of pressure. For subsonic flows a nozzle will have a wider cross-sectional area at its entrance. The cross-sectional area will slope to …
